Abstract

PURPOSE: To reduce the element sensitivity with the simplified circuit constitution as well as to ensure the impedance matching for the input and output by forming the asymmetrical gain unit circuit with two units of the operational amplifier plus 7 units of the resistor.
CONSTITUTION: The circuit consists of 2 units of operational amplifier 8 and 9 plus 7 units of resistors 1∼7 (G1∼G7). Input terminal 10 is connected to the positive input terminal of operational amplifier 8. Then resistor G1, G2, G3, G4, G5, G6 and G7 are connected between terminal 10 and the output terminal of operational amplifier 9, between negative input terminals of 8 and 9, between the negative input terminal of 8 and the output terminal of 9, between the negative input terminal of 8 and common earth terminal 10a, between the negative input terminals of 8 and 9, between the negative input terminal of 9 and common earth terminal 11a, and between the output terminal of 8 and the positive input terminal of 9 respectively.
