Low noise amplification for optical detector arrays

A. Duncan, L. Powers

Research output: Contribution to journalConference articlepeer-review


Detection of low intensity light pulses is accomplished using a three stage amplifier design. A highly sensitive input stage provides a large gain and buffers the sensor from the following stages. An integration stage averages the input signal and holds the output value during data collection. Low impedance output drive capability and noise immunity are provided by a third stage. The combination of these three stages produces a system capable of detecting photocurrent signals in the range of 10-100 nA.
