Abstract
An on-chip temperature sensor for an integrated circuit includes in one embodiment a voltage/current source circuit that provides a reference voltage and a current. A sense signal circuit receives the current of the voltage/current source circuit and provides a sense signal corresponding to the temperature of the integrated circuit. A reference signal receives the reference voltage of the voltage/current source circuit and provides a reference signal having a selectable value. A comparator compares the sense signal of the sense signal circuit to the selectable reference signal of the reference signal circuit and provides a temperature sensor output signal.
