Description of the Invention: [Technical Field] The present invention relates to a measuring device and a measuring method. The present invention is particularly directed to a measuring device and a measuring method for measuring the current consumed by an electronic component. <Prior Art> In the prior art, the test apparatus has a function of measuring the current consumption at the time of stationary of the element under test (for example, refer to Non-Patent Document No. 1-3). The device uses an amplifier that can output a large current as a power supply amplifier for the component to be used. However, when a large electric discharge device can be used, the static consumption current cannot be accurately measured. Therefore, the conventional test apparatus achieves stillness by additionally preparing an amplifier which can measure the current in a low precision even though the current supply capability is low, and switches to the amplifier for the stationary current test during the measurement of the stationary current.

Also, FIG. 1 does not necessarily show the configuration of the test apparatus 10 and the electronic components such as the semiconductor device and the electronic component 10: and the "test device" is an example of the measuring device of the present invention ==electricity = measurement and quiescent current The measurement is performed at a high speed. The detection device 10 includes a pattern generation unit U, an electric number input unit 13, and a determination unit Η. The pattern generation unit U generates a test pattern for indicating a test signal waveform supplied to the electronic unit #100. The power supply unit 12 supplies a power supply voltage to the electronic component 100. The test signal input unit 13 generates a test signal by waveform shaping according to the test pattern, and generates the generated test signal to the electronic component 1 The determination unit 14 outputs the configuration of the power supply unit 12 and the electronic component 1 in accordance with the output signal of the electronic component 100 in accordance with the supplied output signal of the electronic component (10). The power supply unit 12 supplies a power supply voltage to the electronic component 100, and measures the current consumption of the electronic component 100 at rest. The electronic component 100 (% at rest) means utilization. For example, when the operation of the plurality of internal circuits is stopped, the operation of the plurality of internal circuits is stopped, for example, the state in which the current consumption of the electronic component 100 is extremely small. For example, when the battery is stationary, the sleep mode or the Mi mode may be included. In the case of the operation of the electronic component 1 〇〇, it means that the clock is supplied, for example, when the clock is supplied, and the electronic component 1 is in the normal operation state. The power supply unit 12 includes the power output. The terminal 21, the power supply voltage output unit 22, the one-pole switch unit 23, the stationary-time drive unit 24, the stationary-time current measuring unit 25, and the operating-time current measuring unit 26. The power output terminal 21 is connected to the electronic component 1〇〇, and The voltage output from the power supply unit 12 is supplied to the power supply terminal of the electronic component 1. The power supply voltage output unit 22 outputs a power supply voltage Vdd that is stabilized at a predetermined value by, for example, negative feedback control. The diode switch unit 23 has a The forward diodes 31 and the reverse diodes 32 are connected in parallel between the power supply voltage output unit 22 and the wheel output end of the power supply output terminal 21 with the rectification directions being opposite to each other. The diode switch unit 23 functions as It functions as a diode switch, which is formed at the power supply voltage 10 200821587 output portion 22 and the power supply wheel output terminal 2 _sh_ value voltage (for example, q is generated to be equal to the threshold open state, and is generated under the condition of generation: In the disconnected state, in the case of the 甩1 soil 甩 , , , 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 静止 静止 静止 静止The second and second electric poles maintain the same voltage, and the U is separated. Therefore, when the electric Ht100 is operated, the current flowing in the output end of the power supply does not produce the voltage of 21 and the test pattern shown at the output end of the power supply 21 The timing is determined by the driving unit at the time of rest, for example, the switching between the stationary day and the stationary state. In the case of comparison, the 'Electrical® wheel portion 22 is configured. Thereby, the circuit 1 at rest is at a standstill consumption; the response speed of the SC is _-column, and the drive unit 24 at rest can also include the third dry follower circuit 41, which is wheeled by the emperor ^ + ^ The voltage of the music 1 is set between the second voltage regulators 21. The first_device circuit 41 is a terminal-coupler circuit. The follower circuit is an inverting input terminal of the operational amplifier by means of the input, regardless of the load 4: back: t: r. The first voltage circuit 41 can generate the same power as the power supply voltage Vdd from the output terminal due to the non-inversion of the power supply voltage Wd and the negative of the electronic component (10). The first open/close switch 42 is controlled to be in the electronic component! (8) The stationary day is turned off, and is turned on when the electronic component 1 (8) operates. According to the static-time driving unit 24 having such a configuration, by switching the first open/close switch 42, the switching between the operation and the stationary state can be performed. Here, the first open/close switch 42 allows a current consumption at the time of stationary to flow without causing a current during operation. In other words, since the first open/close switch 42 does not allow a large current to flow, it can be a switch capable of high-speed response. Therefore, by using the stationary-time drive unit 24 having such a configuration, it is possible to switch from a high speed to a standstill during operation, and it is possible to start measurement of the power supply current at rest when a short time is started. The stationary current measuring unit 25 measures the output current value output from the stationary driving unit 24 when the electronic component 1 is stationary. The stationary current measuring unit 25 detects, as an example, the inter-terminal voltage of the 帛i current detecting low resistance 43 provided at the output terminal of the operational amplifier constituting the ith voltage circuit 41. And the output current value.电流 When the stationary current measuring unit 25 measures the wheel current value, the current consumption of the electronic component 100 at rest can be measured. The operation-time current measuring unit 26 measures the value of the wheel-out current output from the power source voltage output unit 22 when the electronic component 100 is stationary. In the operation, the current measuring unit 26 measures the output current value by detecting the voltage between the terminals of the second current detecting low resistance 44 provided at the output end of the power supply voltage output unit 22 as an example. The current measuring unit 26 during operation measures the current consumption during the operation of the electronic component ι〇〇 12 200821587 by measuring the output current value. When the electronic component 100 is operated, the power supply unit 12 having the above configuration is supplied from the power supply voltage output unit 22 to the power supply output terminal 21 via the diode switch unit 23. In other words, when the electronic component 100 is operated, the driving unit 24 does not apply a voltage to the power supply output terminal 21 from the stationary state, and the diode switch unit 23 is turned on. Therefore, the current consumed by the electronic component 100 passes through the diode. The switch unit 23 flows between the power source voltage output unit 22 and the power source output terminal 21. f On the other hand, when the electronic component 100 is stationary, the power supply unit 12 supplies the current output from the stationary driving unit 24 to the power supply output terminal 21. In other words, when the electronic component 1 is stationary, the power supply voltage Vdd is applied to the power supply output terminal 21 by the stationary driving unit 24, and the input and output of the diode switch unit 23 become the same potential, and the diode switch unit 23 is provided. Since it is in the off state, the current consumed by the electronic component 100 does not flow into the diode switch unit 23. Thus, the power supply unit 12 uses the diode switch unit 23 provided between the power supply voltage output unit 22 and the power supply output terminal 21 to stop the supply of current from the power supply voltage output unit 22 when it is stationary. As a result, the power supply unit 12 can be switched without providing an open/close switch that allows a large current to flow, so that high speed can be achieved. Therefore, the measurement of the power supply current at rest can be started in a short time. Fig. 3 shows the circuit configuration of an example of the power supply voltage output unit 22. The power supply voltage output unit 22 may include, as an example, a digital/analog converter 51, an amplifying circuit 52, and a feedback circuit 53. 13 200821587 Λ The digital/analog converter 51 is input with, for example, a preset digital value, and generates an analog voltage represented by a digital value (hereinafter referred to as an input electric voltage). The amplifying circuit 52 is based on a voltage fed back through the feedback circuit 53 (hereinafter referred to as a feedback voltage.), and by performing negative feedback amplification on the input voltage output from the digital/analog converter 51, outputting a kind of the input voltage The power supply voltage Vdd that is amplified by the increase is specified. For example, the amplifying circuit 52 may be constituted by an inverting amplifying circuit having an operational amplifier 61, an input resistor 62, and a feedback resistor 63. If the ratio of the feedback resistor 63 to the input resistor 62 is utilized by the inverting amplifying circuit, the above-described The feedback circuit 53 supplies the feedback voltage to the amplifier circuit 52. As an example, the feedback circuit 53 supplies the feedback voltage to the feedback resistor 63 in the inverting amplifier circuit. The feedback circuit 53 operates while the electronic component 100 is operating and at rest. Specifically, since the voltage supplied to the electronic component 100 is stabilized during the operation of the feedback circuit 53, the voltage of the power supply output terminal 21 is supplied as a feedback voltage to the amplifier circuit 52. When the circuit 53 is at rest, the voltage formed by the driving unit 24 at rest is extremely reduced, so that the output voltage of the amplifying circuit 52 is the power supply voltage.

At the non-inverting input end of the second voltage follower circuit 64, the voltage 14 is input to the power supply output terminal 21 by the feedback voltage resistor 66, and the voltage is turned on by the second open/close switch 65, and a pair is used.
