摘要： PROBLEM TO BE SOLVED: To solve a problem that bias voltage dependence characteristics of an ON resistor do not completely become flat according to characteristics deviation of NMOS and PMOS in the conventional circuit if a large amplitude signal is input, distortion occurs in the output signal even though there is a method to temporarily make power supply voltage twice and make a value of the ON resister small, but the method can not make the switching circuit on for a long time.
SOLUTION: In an analog circuit to make a drain terminal or a source terminal of an FET (Field Effect Transistor) as an input or an output terminal, give control voltage on a gate terminal, and perform switching; low distortion characteristics are realized by inserting a capacitor between the source terminal or the drain terminal and the gate terminal, and connecting a resister between the gate terminal and the control terminal, since voltage between the gate terminal and the source terminal/the drain terminal can be maintained large at a time of large signal input.
