ABSTRACT:
A temperature-compensated peak detector circuit which includes a diode connected transistor, the base-collector junction of which is connected across an averaging circuit to a second matched transistor in emitter follower configuration. Appropriate resistances are connected to the collector of the diode connected transistor and to the emitter of the other transistor to make equal the collector currents of the two transistors. As a result, the emitters are at approximately equal voltages. Therefore the adjusted peak voltage of the signal always appears at the emitter of the second transistor regardless of changes in ambient temperature.
