A 1.3 GHz bandwidth 4th order analog filter in a 45nm bulk CMOS process is reported in this work, a cascade of two Rauch bi-quads based on an unique combination of both feedforward and miller compensation to achieve a high unity gain bandwidth.Abstract:
A 1.3 GHz bandwidth 4th order analog filter in a 45nm bulk CMOS process is reported in this work. The filter is a cascade of two Rauch bi-quads. The operational amplifiers for these biquad cells are based on an unique combination of both feedforward and miller compensation to achieve a high unity gain bandwidth of 4.5GHz, a high dc gain of 45dB and a good phase margin of 75 degrees. Post-layout simulations of the filter shows a 3dB cut off frequency of 1.3GHz with an IIP3 of + 12dBm and a total in band integrated noise voltage of 660μVRMS. The total dc power consumption of this filter is 24 mW at a 1.1V power supply.read more
