| Abstract: | The operating principle of photodetector readout circuit(ROIC) based on capacitive transimpedance amplifiers(CTIA) and correlated double sampling(CDS) is presented in this paper.The sequential relationship of control signal is discussed.Based on all of these,a control circuit with tunable parameters for ROIC is designed.This circuit is simulated by software Cadence,and the layout is optimized.Then the chip is produced by the foundry.The measurement of this chip is done.The experiment shows that the control ... |
