Abstract
Described herein are variable-gain amplifier configurations that include a multi-input gain stage, a cascode buffer, and a bypass block. Degeneration switching blocks can be used for the entire multi-input gain stage or for individual input nodes of the multi-input gain stage. This advantageously reduces or eliminates performance penalties in one or more gain modes. The variable impedances can be configured to improve linearity of the amplification process in targeted gain modes. The variable gain amplifier can be configured to provide a low-loss bypass mode in a low gain mode to improve signal quality.
