Analysis, design, and characterization of an E-band Variable Gain Amplifier (VGA) in SiGe BiCMOS commercial technology is presented. VGA topologies are compared in terms of their capability to contribute to receiver linearity and dynamic range.

Abstract
Analysis, design, and characterization of an E-band Variable Gain Amplifier (VGA) in SiGe BiCMOS commercial technology is presented. VGA topologies are compared in terms of their capability to contribute to receiver linearity and dynamic range. The proposed VGA is based on a Gilbert multiplier cell exploiting current cancellation to enhance control range and linearity. A 1 dB bandwidth ranging from 80 to 100 GHz, a 24 dB gain control range and a -11.5 dBm input 1 dB compression point have been measured.| File | Dimensione | Formato | |
