Abstract
An image rejection mixer includes a first mixer, a second mixer, a first output adjust circuit, and a second output adjust circuit. The first mixer is coupled to receive an input RF signal and a local oscillator signal and includes a first mixer stage and a first output load stage. The second mixer is coupled to receive the input RF signal and a phase-converted local oscillator signal and includes a second mixer stage and a second output load stage. The first output adjust circuit is coupled to the first output load stage for modifying the signal waveform of a first output signal of the first mixer. The second output adjust circuit is coupled to the second output load stage for modifying the signal waveform of a second output signal of the second mixer. In this manner, the near-perfect image rejection result in the final IF signal can be obtained.
