|Title:||A High IIP2 SAW-Less Superhetero-dyne Receiver with Multi-Stage Harmonic Rejection||Authors:||Madadi, Iman; Tohidian, Massoud; Cornelissens, Koen; Vandenameele, Patrick; Staszewski, Robert Bogdan||Permanent link:||http://hdl.handle.net/10197/8500||Date:||Feb-2016||Online since:||2017-05-11T09:55:22Z||Abstract:||In this paper, we propose and demonstrate the first fully integrated surface acoustic wave (SAW)-less superheterodyne receiver (RX) for 4G cellular applications. The RX operates in discrete-time domain and introduces various innovations to simultaneously improve noise and linearity performance while reducing power consumption: a highly linear wideband noise-canceling low-noise transconductance amplifier (LNTA), a blocker-resilient octal charge-sharing bandpass filter, and a cascaded harmonic rejection circuitry. The RX is implemented in 28-nm CMOS and it does not require any calibration. It features NF of 2.1-2.6 dB, an immeasurably high input second intercept point for closely-spaced or modulated interferers, and input third intercept point of 8-14 dBm, while drawing only 22-40 mW in various operating modes.||Funding Details:||European Research Council||Type of material:||Journal Article||Publisher:||IEEE||Journal:||IEEE Journal of Solid-State Circuits||Volume:||51||Issue:||2||Start page:||332||End page:||347||Copyright (published version):||2015 IEEE||Keywords:||Bandpass filter (BPF); Charge-sharing; Discretetime; IIP2; Process-scalable; Receiver; Surface acoustic wave (SAW)-less; Superheterodyne; Mixers; Capacitors; Calibration; Surface acoustic waves; Radio frequency||DOI:||10.1109/JSSC.2015.2504414||Language:||en||Status of Item:||Peer reviewed||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
