A low-voltage, highly linear, integrated, active-RC filter

Abstract

A 1-V, highly linear, integrated, active-RC, filter incorporating the ability to change both its transfer function (Chebyshev, elliptic) and its bandwidth (5 MHz, 10 MHz), is presented. The filter utilizes digitally controlled polysilicon resistor banks to account for variations of its corner frequency. A filter prototype, fabricated in a 0.12 /spl mu/m… (More)
