Abstract
A bias voltage monitoring circuit is disclosed which comprises a first device coupled between a positive high voltage power supply (VDD) and a first node, a second device coupled between the first node and a second node where the bias voltage is applied, and a pad coupled to the first node, wherein the first and second devices form a voltage divider and a voltage measured at the pad reflects the bias voltage, and the first device and the second device is so chosen that a voltage at the first node is always positive for a given range of the bias voltage.
