ABSTRACT:
Provided is a method of acquiring a high linear characteristic and a low distortion in a transconductor (operational transconductance amplifier), especially, in a triode region type transconductor among CMOS transconductors. A resistance is inserted in a source or a drain of an input triode transistor. The transconductor has a simple circuit structure, and has a large linear region, constant transconductance and low total harmonic distortion (THD) characteristic within an error region.
