CIN, said operational amplifier in the linear region when any one of the equivalent input capacitance (the other input is grounded).

CIN said operational amplifier work linear zone in any one input port of another input capacitance (equivalent ground).

　　Results in the use process in the instrument measuring appliance to be able to involve to the measuring range results in the question. In order to obtain the fixed voltage to result in the output, must change the operational amplifier to result in the enlargement factor. For example: When some ope

　　CIN said operational amplifiers in linear area equivalent capacitance of any input (another input ground).

　　CIN said operational amplifier in any equivalent capacitance of an input terminal when the linear area (another input ground).
