Tohidian, M. (author), Madadi, I. (author), Staszewski, R.B. (author)The zero/low intermediate frequency (IF) receiver (RX) architecture has enabled full CMOS integration. As the technology scales and wireless standards become ever more challenging, the issues related to time-varying dc offsets, the second-order nonlinearity, and flicker noise become more critical. In this paper, we propose a new architecture of...journal article 2017

Madadi, I. (author), Tohidian, M. (author), Cornelissens, Koen (author), Vandenameele, Patrick (author), Staszewski, R.B. (author)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...journal article 2016

Madadi, I. (author), Tohidian, M. (author), Staszewski, R.B. (author)A complex quadrature charge-sharing (CS) technique is proposed to implement a discrete-time band-pass filter (BPF) with a programmable bandwidth of 20–100 MHz. The BPF is part of a cellular superheterodyne receiver and completely determines the receiver frequency selectivity. It operates at the full sampling rate of up to 5.2 GHz corresponding...journal article 2015
