Abstract
The present invention provides a signal-processing circuit including an amplification module and an analog-to-digital conversion module, wherein the amplification module includes a first input terminal for receiving an input signal, a second input terminal for receiving a reference signal, and an output terminal coupled to the analog-to-digital conversion module. Furthermore, the input signal and the reference signal are amplified by the amplification module individually, and an amplified signal is output to the analog-to-digital conversion module through the output terminal, and then the amplified signal undergoes analog-to-digital conversion by the analog-to-digital conversion module. The first amplification coefficient of which the input signal is amplified by the amplification module and the second amplification coefficient of which the reference signal is amplified by the amplification module are opposite in sign. The voltage range of the amplified signal is substantially equal to the scale of the analog-to-digital conversion module.
