In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-Q switched capacitor pseudo ۲-path filter.  The filter is a sixth–order Chebyshev band-pass filter operating at sampling frequency of ۱MHz and center frequency of ۲۵۰ kHz with a quality factor of ۵۰. The proposed filter has both low-voltage and high speed properties of the auto zeroed integrators and accurate center frequency of N-path band-pass filters. The operating voltage is ۱.۵v with no use of voltage bootstrapper circuit. Simulation is done using HSPICE and ۰.۲۵µm CMOS technology.
