A programmable temperature sensing circuit includes a comparator, first and second CTAT sensing elements, first and second PTAT reference circuits, and a selection circuit. When a selection signal is a first logic state, an output terminal of the first PTAT reference circuit is coupled to the second CTAT temperature sensing element for providing a first threshold voltage to the second input of the comparator. When the selection signal is a second logic state different from the first logic state, a series-connection of the first PTAT reference circuit and...
