Abstract

A voltage reference circuit includes: a Zener diode and a synchronization circuit coupled to a cathode of the Zener diode. The synchronization circuit includes a first circuit and a second circuit, where each of the first circuit and second circuit includes: a current source coupled between a supply voltage node and a first node; a first switch coupled between the first node and a reference voltage node; a first capacitor coupled between the first node and a second node; a second switch coupled between the second node and the supply voltage node; and a third switch coupled between the second node and the cathode of the Zener diode.
