ABSTRACT:
N-channel field effect transistor Proportional To Absolute Temperature (N-PTAT) cells are connected to a first supply voltage and P-channel field effect transistor Proportional To Absolute Temperature (P-PTAT) cells are connected to a second supply voltage. A coupling circuit connects at least one of the N-PTAT cells to at least one of the P-PTAT cells. These circuits can be used to provide a voltage reference and/or a supply voltage level detector. Related operating methods are also described.
