Analysis Design

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.

Wave Matching

A traveling wave matching (TWM) network is proposed for broadband variable gain amplifier design. The TWM network lessens input return loss and noise figure dependence on VGA’s gain, which is adjusted by biasing of the gain control circuit. A wide band (DC to 12 GHz) VGA with the novel TWM network as input matching is implemented in 2μm InGaP/GaAs HBT (fT of 29.5GHz) technology with die size of 1×2 mm2. As gain control voltage sweeps, the VGA shows a gain tuned from -15 dB to 15 dB and an average noise figure ranging from 8dB to 6.5dB, while S11 (lower than -20dB) and S22 (lower than -10dB) almost unchanged over the operation frequency band.

Gain Stage

A using SiGe HBT variable gain amplifier (VGA) with filtering for wireless receiver system is presented in this paper. The VGA consists of three stages. The first stage is the gain control stage, and the second stage is the fixed gain stage. The third is the GM-C filter. The VGA is driven by a 3.3-V power supply, and linear gain control range varying is from 26 dB to 62dB. When control voltage varies from 0 to 1.8V. The input 1-dB compression point is -4dBm at minimum gain. The VGA is fabricated in a 0.5 μm = 80GHz and =90GHz silicon germanium heterojunction transistor technology.
