초록
Provided is a transconductor capable of eliminating a direct current (DC) offset component of a signal and compensating a mismatch of the signal. The transconductor includes amplifiers of simple circuit structures, and a common mode control DC offset elimination circuit. The transconductor includes a common mode control DC offset elimination circuit unit receiving input/output voltages to stabilize the current supplying and the output DC value, a first amplifier and a second amplifier reducing a mismatch in a transconductor circuit and increasing an output resistance, in order to prevent a signal distortion or a wrong operation of the circuit that is caused by the mismatch signal and unstable DC voltage.
