Abstract

A novel large input range source-follower based filter architecture is proposed offering a increased 1-dB compression point, without increased power consumption. An alternative feedback mechanism enables single-ended use and simplifies the bias scheme. Simulation has confirmed a 250MHz second order filter stage consuming 40uA @ 1.2V supply in a 0.13um CMOS technology with 1-dB compression point at a differential peak to peak input amplitude of 1.4V, more than doubling the input range of previous implementations with similar power dissipation.
