A4-Channel Photocurrent Detector with 118dB-DR TIAs

摘要：

In this paper, a 4-channel photocurrent detector is described which is used in the field of photoelectric detection. Each channel of the detector consists of TIAs and voltage comparator, and current detection threshold can be set by external voltage. The TIA has measured 1.5mA input current overload capacity and 1.9nArms equivalent input noise current level. The detector is processed in 2um all-NPN bipolar process technology. The die size is 2.13mm×l.31mm. The total power dissipation is 60mW at power supply of ±5V.
