Abstract
A receiver circuit includes a mixer receiving an RF signal encoding an information signal. The mixer receives a number of multiphase oscillator signals and generates multiphase baseband signals. The receiver circuit also includes a variable gain circuit receives the multiphase baseband signals, generates a first output signal having a first distortion, and a second output signal having a second distortion. The variable gain circuit is configured to generate a reduced distortion output signal based on the first and second output signals.
