Abstract
An analytic model for current gain as a function of optical input power in heterojunction bipolar phototransistors is developed. The model provides excellent agreement with the dc measurements of a resonant-cavity-enhanced heterojunction bipolar phototransistor. The model is extended to explain small-signal results.
