Abstract
A temperature sensing read-out system for an integrated circuit includes a temperature sensor circuit for providing an analog signal representative of temperature and a high order sigma delta analog to digital converter responsive at its input to the analog signal representative of temperature to provide at its output a digital signal representative of temperature; the temperature sensing read-out system may be reconfigurable and include in addition to the temperature channel and auxiliary channel accompanied by a switching circuit for interconnecting in a temperature mode the temperature channel to the high order sigma delta analog to digital converter, and for interconnecting in one or more auxiliary modes the one or more auxiliary channels to the same sigma delta analog to digital converter.
