A novel structure for realization of a pseudo two path band-pass filter

In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-speed and accurate switched capacitor pseudo 2-path filter. The filter is a sixth-order Chebyshev band-pass filter operating at sampling frequency of 1MHz and center frequency of 250 kHz with a quality factor of 50. The circuit is simulated using HSPICE and 0.25µm CMOS technology.
