| Abstract: | This paper proposes a new transconductor circuit which adopts CMOS double pairs. It has a transconductance linearly variable by a gate voltage, and suitable for application to highly linear continuous-time filters. Simulation results show that the total harmonic distortion (THD) of the output current is less than 0.5% for the differential input signal of 2.3V(peak-to-peak)when the supply voltages are 5V. |
