Study and Design of Integrated Mixer and LNA Topologies for WiFi and Wideband Systems with a High Immunity to Parasitic Signal Feedthrough

In the recent years, progress in wireless technology has required high-quality receiver designs that comprise low power, low cost, and high integration. Low noise amplifiers (LNA) and mixers are essential components of the design of the receiver. During this project, three integrated circuits solutions are developed which includes four mixer circuits and two LNA topologies. The folded mixer that is developed for WiFi applications provides high isolations and improved linearity. The self-biased mixer, bulk-injection mixer, switched-transconductance mixer, and LNA support the use of this design in low-power and wideband front-end applications.
