Abstract
A digital receiver includes an analog front-end circuit, an automatic-gain controller, a compensation circuit, and a demodulator. The analog front-end circuit receives an input signal, adjusts an average amplitude of the input signal, and converts the adjusted input signal to generate a digital signal according to a control signal. The automatic-gain controller is coupled to the analog front-end circuit for generating the control signal feedback to the analog front-end circuit according to the digital signal. The compensation circuit is coupled to the analog front-end circuit for detecting an average amplitude of the digital signal to generate a detecting result and for determining whether to compensate the average amplitude of the digital signal to generate a compensated digital signal according to the detecting result. The demodulator is coupled to the compensation circuit for demodulating the compensated digital signal to generate an output signal.
