Abstract
A signal processing circuit has a first mixer, a first amplifier, and a pulling effect mitigation circuit. The first mixer mixes a first input signal and a first oscillation signal to generate a first output signal, wherein the first oscillation signal is generated by dividing a frequency of a reference clock with a frequency dividing factor. The first amplifier amplifies the first output signal, and generates an amplified output signal at an output terminal of the first amplifier. The pulling effect mitigation circuit is coupled to the output terminal of the first amplifier, and generates a compensation signal to the output terminal for reducing at least an Nharmonic of the amplified output signal, wherein a value of N is equal to the frequency dividing factor.
