Abstract

The design and implementation of a CMOS current-mode fourth-order Butterworth continuous-time leap-frog (LF) multiple loop feedback (MLF) lowpass filter is described. The filter is implemented using a fully-differential linear, low voltage and low power operational transconductance amplifier (OTA). PSpice simulations using a standard TSMC 0.18μm CMOS process with 1.5V power supply have shown that the cut-off frequency of the filter ranges from 240MHz to 300MHz and dynamic range is about 58dB at 240MHz of cut-off frequency. The power consumption of the filter is only from 22.3 to 55mW. The total output noise density is about 390nA/√HZ.
