  In this work the low-voltage high-speed auto zeroed integrator characteristics is improved by utilizing the non-linear properties of switches. Based on this improvement a newly designed structure for a low-pass filter is presented. The designed filter is a fourth order Chebyshev with pass band frequency of 500 KHz and sampling frequency of 5 MHz. Based on this method a fast and accurate sample and hold structure is introduced. The designed work is simulated using 0.25µm CMOS technology at 1.2 V supply voltage. Manuscript profile
