Abstract
A proportional to absolute temperature (PTAT) generator generates a current PTAT (IPTAT) and a fractional VBE in a first regulation loop. A level shifting voltage-to-current converter is arranged as a second regulation loop and is operable to generate a current ZTC (IZTC) and/or a voltage ZTC (VZTC). Both regulation loops are nested into each other. In an embodiment, the voltage-to-current converter is operable to sum a scaled voltage PTAT (VPTAT/Y) with the fractional VBE (VBE/X) to generate the ZTC signal. In another embodiment, the voltage-to-current converter is operable to sum a delta voltage threshold (ΔVTH) with the fractional VBE (VBE/X) to generate the ZTC signal.
