Delta Reference, the Latest High Temperature Compensated Voltage Reference Concept

This paper introduces the newest proprietary concept called Delta-Reference voltage generator. It is able to generate sub-1V, high temperature compensated voltage reference implemented on silicon carbide (SiC) devices. Hereby, we experimentally demonstrate the functionality of Delta-Reference concept based on a large variety of temperature-dependent SiC devices. Delta-Reference is comparable to the well-known Bandgap-Reference in terms of temperature coefficient (TC), but our new approach is more versatile and comes with additional benefits, being a right candidate for a new generation of voltage reference addressed to high temperature, power management, and space applications.
