A Blocker-Tolerant Non-Uniform Sub-Sampling Receiver With a Non-Uniform Discrete

Abstract

A non-uniform (NU) sub-sampling receiver (RX) with a NU discrete-time FIR (NU DT FIR) filter can create multiple tunable frequency notches both near and far from the passband via predesigned NU sampling clocks and filter coefficients. NU DT finite impulse response (FIR) acts as an anti- aliasing (AA) filter for a nonuniformly sampled signal which relaxes the subsequent ADC speed and dynamic range (DR). To save power and area and to improve linearity, the FIR filter is implemented in the current
