A software-defined radio (SDR) receiver with baseband programmable RF bandpass filter
(BPF) and complex impedance match is presented. The passive mixer-first architecture used …

This article reviews the main parts of a software-defined radio (SDR) to emphasize several
possible implementations of both receivers and transmitters. We describe solutions for …

In this paper, a class of passive mixer-first, LNA-less receivers is analyzed in depth.
Quadrature passive mixers are shown to present the impedance of their baseband port to …

A wideband noise-cancelling low-noise amplifier (LNA) without the use of inductors is
designed for low-voltage and low-power applications. Based on the common-gate-common …

This paper proposes and describes a new software and application programming interface
view of an RF transceiver. It demonstrates benefits of using highly programmable digital …

A low area fully reconfigurable multi-band LNA array based on active feedback amplifiers
with mixed resistive and switched inductor loads is presented. The 90 nm baseline digital …

A CMOS direct-conversion receiver with only one signal path is reconfigurable from 2 to 6
GHz in the RF band and from 3.6 to 54 MHz in the channel bandwidth. By employing a …

A wideband high dynamic range frequency hopping transceiver is presented for the Joint
Tactical Radio System (JTRS) project at the University of California, San Diego. The …
