摘要： A transconductor for substantially canceling or reducing a direct current (DC) output offset and a method thereof are provided. The transconductor includes a differential amplifier, a sensing circuit, and a feedback current generation circuit. The differential amplifier outputs output signals having a DC output offset therebetween due to a difference between input signals or a mismatch between input terminals. The sensing circuit senses the DC output offset and outputs a sensing signal. The feedback current generation circuit provides a feedback current for adjusting a level of the output signals to the input stage of the differential amplifier in response to the sensing signal. Accordingly, the transconductor substantially cancels or reduces the DC output offset between the output signals in response to the feedback current.
