Given the plethora of low GHz radio standards and frequency bands, multi-band software
defined radio receivers are coming up. Such digital intensive radios are implemented in …

Recent developments in CMOS passive mixers have demonstrated a number of new and
useful capabilities, including dynamic RF port impedance control and filter up-conversion …

By employing two passive-mixer-based downconversion paths, a recently proposed noise
cancelling receiver achieves a low-noise figure and tolerates most out-of-band blockers up …

Carrier aggregation is an attractive approach to increasing the data rate in wireless
communication. This paper describes an efficient carrier aggregation receiver architecture …

This article presents an agile passive-mixer-first superheterodyne RF front-end that utilizes a
gigahertz acoustic filter as its intermediate-frequency (IF) load-essentially a mixer-first …

A frequently occurring subcircuit consists of a loop of a resistor (R), a field-effect transistor
(FET), and a capacitor (C). The FET acts as a switch, controlled at its gate terminal by a clock …

A synthetic transmission-line N-path bandpass filter technique that lowers the in-band
insertion loss and increases the out-of-band rejection of the traditional N-path filter is …

In Part I of this paper, we introduce useful analysis that leads to a simple signal flow graph
(SFG), which captures the FET-RC circuit's action completely across a wide range of design …

A current-mode 60-GHz direct-conversion receiver, which can break performance tradeoffs
among bandwidth, noise figure (NF), and linearity is designed and realized in 65-nm CMOS …

This paper presents a four-phase passive mixer-first receiver using a common-gate (CG)
trans-impedance amplifier (TIA), instead of a conventional shunt-feedback amplifier. The …
