Granted: 2023-08-11
Abstract: Described herein are variable gain amplifiers and multiplexers that embed programmable attenuators into switchable paths that allow signals in a high gain mode to bypass attenuation. This advantageously reduces or eliminates performance penalties in the high gain mode. The programmable attenuators can be configured to improve linearity of the amplification process through pre-LNA attenuation in targeted gain modes. In addition, described herein are variable gain amplifiers with embedded attenuators in a switching network. The attenuators can be embedded onto switches and can be configured to have little or no effect on a noise factor in a high gain mode because the switching network can provide an attenuation bypass in a high gain mode and an attenuation in other gain modes. The programmable attenuators can be embedded onto a multi-input LNA architecture.
