摘要
This paper describes a low-voltage and low-power transconductance amplifier and its application to third-order elliptic low-pass filter. The bulk-driven MOS transistor technique is used to provide low supply voltage operation and rail-to-rail input voltage common mode. The performance of the proposed filter is expressed through PSPICE simulators using TSMC 0.18 mu m n-well CMOS process. Simulation results show that the filter using proposed circuit consumes 36 mu W for power supply of a 0.5 V and has total harmonic distortion 1 % for input signal of 480 mV(P-P).
