Novel Voltage-controlled Amplifiers for Multistandard Integrated Radio Receivers

Abstract

This paper proposes a new architecture for transconductance (Gm)-based variable-gain amplifiers (VGA) that is better suited for multi-standard radio receivers than the classical two-Gm structure: its bandwidth and linearity are largely independent of the gain setting and both the gain range and the bandwidth can be programmed through digital controls… (More)
