In this paper an approach for the design of low-voltage analog Active-RC filers is presented. This technique is based on the use of different common mode levels at the opamp inputs and the filter inputs and outputs. A design example of a 600mV supply voltage 4th order low-pass analog filter for UMTS receivers is reported. The filter is designed in a 0.13μm CMOS technology with a 600mV supply voltage. The filter features a wide swing performance (THD=40dB@800mVpp,differential output signal amplitude), and high dynamic range (47 dB). © 2006 IEEE.

Abstract
In this paper an approach for the design of low-voltage analog Active-RC filers is presented. This technique is based on the use of different common mode levels at the opamp inputs and the filter inputs and outputs. A design example of a 600mV supply voltage 4th order low-pass analog filter for UMTS receivers is reported. The filter is designed in a 0.13μm CMOS technology with a 600mV supply voltage. The filter features a wide swing performance (THD=40dB@800mVpp,differential output signal amplitude), and high dynamic range (47 dB). © 2006 IEEE.
