چکیده
|
Abstract in this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-q 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 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 1.5v with no use of voltage bootstrapper circuit. simulation is done using hspice and 0.25µm cmos technology.
