Abstract

PURPOSE: To achieve voltage amplification with good linearity and without offset through a simple constitution, by connecting two current circuits of series connection of a constant current source and a resistor in parallel and making the current ratio of two constant current sources and the resistance ratio of two resistors constant.
CONSTITUTION: Voltages I1R1 and I2R2 appear at resistors R1, R2 terminals in current circuits, where I1 is a current of a constant current source 11 of the 1st current circuit and I2 is a current of a constant current source 12 of the 2nd current circuit. When the ratio I1/I2 is made always constant, since the ratio of R1∼R2 can be taken freely, the ratio I1R1/I2R2 can be determined by design and a linear relation exists between the I2R2 and I1R1. To a voltage V1 desired to be amplified, the current I2 proportional to the current I1 flowing to the current circuit including the resistor R1 is made and the other resistor R2 is inserted in the circuit, allowing to achive the volgage V1 without offset and with good linearity.
