Abstract: 
A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has ‎been designed to be used as part of a cellular GSM (Global System Mobile) receiver. ‎A Gaussian-to-6dB filter of the order of seven is chosen and a second order function ‎is added to reduce the group delay variations around 1m#s. The filter uses a fully ‎differential topology to increase the dynamic range and reduce the clock feed-through ‎noise and the distortion due to low voltage amplifier. Using a chopper stabilization ‎technique in opamp design reduces the flicker noise. In order to reduce the charge ‎injection two methods of delayed clock phases and dummy switches are used. The ‎filter is realized by cascading the biquad sections. The filter has been designed in a ‎‎0.35 m#m CMOS technology and simulated with Hspice using BSIM 3V3model. The ‎filter operates at 2MHz sampling frequency and 1MHz chopping frequency with a ‎corner frequency of 100 KHz and 7 mW power consumption‏.‏
