Abstract

In this paper, a 4th-order low-pass Gm-C filter is presented. For the design of operational tranconductance amplifier(OTA), it adopts the techniques of current division and current cancellation. These techniques can help to achieve a low transconductance value. For the architecture of the 4 th-order Gm-C filter, it consists of two biquads. The two biquads are cascade connected. The Gm-C low-pass filter has been implemented under 0.5 μm CMOS process model. The final simulation results show the cutoff frequency of the filter is 100Hz and the stop-band attenuation is larger than 60dB. The power consumption is lower than 1mW and the total harmonic distortion(THD) is -55dB.
