A Highly Selective Receiver With Programmable Zeros and Second-Order TIA Mohamma

Abstract

This article presents a wideband blocker tolerant receiver (RX) for fifth-generation (5G) user equipment applica- tions. Two programmable zeros around the channel bandwidth are introduced to sufficiently suppress the close-in blockers of 5G applications. Since the effect of zeros gradually diminishes at larger out-of-band offset frequencies, an auxiliary current- sinking path is also introduced to reduce the RX input impedance at far-out offset frequencies. Moreover, a simple second-order transi
