Abstract
A signal receiving circuit receives an input signal and includes a radio frequency (RF) front-end circuit, a filter circuit, an amplifier circuit, an analog-to-digital converter (ADC), a compensation circuit, an adder circuit, and a control circuit. The RF front-end circuit down-converts the input signal to generate a down-converted signal. The filter circuit filters the down-converted signal to generate a filtered signal. The amplifier circuit amplifies, according to a control signal, the filtered signal with a gain to generate an amplified signal. The ADC converts the amplified signal into a first digital code. The compensation circuit generates a compensation code according to at least one of the control signal and the gain. The adder circuit generates a second digital code according to the compensation code and the first digital code. The control circuit generates the control signal according to the second digital code.
