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 mum CMOS process with 1.8 V power supply have shown that the cut-off frequency of the filter ranges from 455 MHz to 780 MHz and dynamic range is about 58 dB. The group delay is less than 5% over the whole tuning range; the maximum power consumption of the filter with gain boost is only 240 mW.
