摘要：A circuit, including: a photodetector including a first readout terminal and asecond readout terminal different than the first readout terminal; a first readout circuitcoupled with the first readout terminal and configured to output a first readout voltage;a second readout circuit coupled with the second readout terminal and configured tooutput a second readout voltage; and a common-mode analog-to-digital converter (ADC)including: a first input terminal coupled with a first voltage source; a second inputterminal coupled with a common-mode generator, the common-mode generatorconfigured to receive the first readout voltage and the second readout voltage, and togenerate a common-mode voltage between the first and second readout voltages; and afirst output terminal configured to output a first output signal corresponding to amagnitude of a current generated by the photodetector.
