SWITCHING OF RESISTOR EPI BIASING FOR REVERSED RESISTOR CONNECTION IN OFFSET ELEMENT CANCELLATION SYSTEM

摘要

A method of improving voltage detection accuracy and precision by employing a switchable resistor epi bias design, which consists of switches to control connection of resistor epi bias. By constantly maintaining the resistor epi bias to its own resistor terminal bias via switches, higher accuracy detection than conventional resistor bias method can be achieved.
