Abstract
An embodiment for an integrated circuit for temperature detection includes: a closed loop circuit branch including: a first bipolar junction transistor (BJT), a first resistor coupled between a first base of the first BJT and a junction node, and an amplifier having an output coupled to the junction node and a non-inverting input coupled to a collector of the first BJT; and an open loop circuit branch including: a second BJT, a second resistor coupled between a base of the second BJT and the junction node, a third resistor coupled between the base of the second BJT and ground, and a comparator having an inverting input coupled to a collector of the second BJT and an output configured to provide a digital voltage signal that corresponds to a temperature reading.
