摘要 本文提出了一种新的跨导器结构,它采用CMOS复合对管实现,可以通过调节栅极电压改变跨导器的跨导值,适合应用于高线性的连续时间滤波器.仿真结果表明,在供电电压为5伏,输人差分信号峰峰值为2.3伏的情况下,可以达到小于0.5％的总谐波失真. 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.
