Abstract
A high-voltage sensing device providing full galvanic isolation between a high-voltage domain and a low-voltage domain, wherein the circuit topology of the device resembles that of a Wheatstone bridge, the Wheatstone bridge employing at least one voltage-controlled semiconductor resistor, wherein the circuit also comprises a reference source connected directly to the Wheatstone bridge and the device comprises a number of shielding structures to electrically isolate the high-voltage domain from the low-voltage domain.
