Abstract
Provided is a transconductor circuit for compensating distortion of an output current without reducing the size of chips and operation speed characteristics. The transconductor circuit includes a main circuitry which is a differential pair with source degeneration and to which a predetermined input voltage is applied, an auxiliary circuitry which is connected to nodes of the main circuitry to compensate the distortion of the output current, a variable voltage supply which controls a depth or degree of a distortion compensation operation for the output current, and a current source which supplies the main circuitry with constant bias.
