Abstract:
1. An amplifying/digitalizing circuit, comprising: an amplifier, having an input end and an output end; and a control circuit, coupled to the input end of the amplifier and directly connected to the output end of the amplifier, wherein when the amplifying/digitalizing circuit is operated under an amplifying mode, the control circuit has a first configuration to receive a first input signal and makes the amplifier generate an output voltage at the output end according to the first input signal and an amplification factor; and when the amplifying/digitizing circuit is operated under an ADC mode, the control circuit has a second configuration to receive a second input signal and makes the amplifier generate a comparison result according to the second input signal and the output voltage; wherein when the amplifying/digitalizing circuit is operated under a reset mode, the control circuit has a third configuration to reset the amplifier, and the control circuit comprises:
