【発明の詳細な説明】 不発明は集積回路に関する。[Detailed description of the invention] The invention relates to integrated circuits.

池のように内部インピーダンスの冒い電源回路で装置′
ｆｃ駆動する場合。In recent years, advances in semiconductor technology have led to lower power consumption in devices, and electronic calculators that run on solar cells have become obsolete. In addition to general electrical characteristics, power consumption at low voltage is an important issue for devices that operate on solar cells. Devices with power circuits that have high internal impedance, such as solar cells
When using fc drive.
電源定圧−電流特性に負性抵抗の頷同があれば使用上大
きな問題となる。If there is a negative resistance in the power supply constant voltage-current characteristics, it will be a big problem in use.

インピーダンス全表わしてｂる。FIG. 1 shows the power supply characteristics including negative resistance characteristics. 1 is a curve of power supply voltage versus power supply current, 2t is a straight line showing the output current versus output voltage of the solar cell, and b represents the total internal impedance of the battery.

正常な動作ができなくなる。Points 3 and 4, where the curve 1 intersects with the straight line 2, are stable points in terms of Wataru, and it is possible to continue this state. 50 points is a small point and does not exist as a steady state. Point 4 is the point we want to use for actual operation. Point 3 indicates that the power supply voltage does not reach a normal value because the current consumption flows abnormally at low voltages, and the output voltage of the solar cell is suppressed to a small degree. Power sources other than solar cells, such as manganese batteries and oxidized batteries, do not have this problem because their internal impedance is relatively low. The occurrence of a large peak of current at 6 in FIG. 1 does not become a 't'aVc problem unless it is in the normal operating range. If the voltage of the power supply 1 falls below the operating range, the current peaks as shown in 6 may occur, causing the device M to become unable to operate according to the procedure determined by the original programm, etc., resulting in a runaway state, or a specific current flow. 0, which occurs when the device stops while the current is flowing.For normal applications, it was not seen as a problem at all because it was outside the operating voltage range, but in the case of solar cells, etc., this current peak causes When the specified voltage is not applied to the device,
Normal operation becomes impossible.
