Abstract

The design and implementation of a CMOS continuous-time multiple loop feedback (MLF) leap frog (LF) filter is described. The filter is implemented using a fully?differential linear, low voltage operational transconductance amplifier (OTA). PSpice simulations using a standard TSMC 0.18?m CMOS process with 1.8V power supply have shown that the cut-off frequency of the filter ranges from 455MHz to 780MHz and dynamic range is about 58dB. The group delay is less than 5% over the whole tuning range; the maximum power consumption of the filter with gain boost is only 240mW.
