Abstract
A signal receiving circuit includes an amplifier, a mixer, and a first controlling circuit. The amplifier includes: an input stage for receiving an input signal to generate a first signal; a gain stage coupled to the input stage for generating an output signal according to the first signal; and an output stage coupled to the gain stage for adjusting a spectral response of the amplifier according to a first adjusting signal. The mixer is coupled to the gain stage for generating a converted signal according to the output signal. The first controlling circuit is coupled to the mixer for detecting the converted signal to generate the first adjusting signal to adjust the spectral response of the amplifier.
