Abstract

Tracking the Icq (quiescent collector current) of a class AB amplifier when the thermal tracking device is in a non-ideal location or when the track- ing device is not located on the same plane as the device to be tracked. Ideally one would like the tracking device to be located in direct contact with the device to be tracked, to prevent thermal runaway and maintain Idq regulation, but this is usually not practical. This non-ideal location usually results from manufacturing considerations.
