摘要：
A high-gain, high-speed differential preamplifier is described, in which a current source is coupled to one input of a differential amplifier and the other input of the differential amplifier is coupled to a sensor. In one implementation, the current source includes a field effect transistor operating in saturation mode and a bipolar junction transmitter in an emitter follower configuration.
