Receiver

Abstract

A receiver includes a low noise amplifier, a gain stage circuit, a first mixer coupled to the gain stage circuit through a first node and that performs frequency down conversion, based on a first local oscillator (LO) signal and a second LO signal inverted from the first LO signal, a second mixer coupled to the gain stage circuit through a second node and that performs frequency down conversion, based on a third LO signal orthogonal to the first LO signal and a fourth LO signal inverted from the third LO signal, a first sink switch coupled to the first node and turned on based on a first control signal defined as a sum of the third and fourth LO signals, and a second sink switch coupled to the second node and turned on based on a second control signal defined as a sum of the first and second LO signals.
