摘要:
The disclosure provides a receiver with reduced noise. The receiver includes a photodiode that generates an input signal in response to received light pulses. A pixel switch is coupled to the photodiode. An operational amplifier is coupled to the photodiode through the pixel switch. A feedback capacitor and a reset switch are coupled between a first input port and an output port of the operational amplifier. A switched resistor network is coupled to the output port of the operational amplifier. A first switched capacitor network is coupled to the switched resistor network and samples a reset voltage. A second switched capacitor network is coupled to the switched resistor network and samples a signal voltage. A subtractor receives the reset voltage and the signal voltage, and generates a sample voltage. The second switched network comprises two or more capacitors.
