Abstract :
A novel high impedance JFET high voltage follower combined with ADC driver and a dedicated error compensation feedback is discussed in this paper. Proposed circuit builds around required ADC driver and its transfer curve by adding few low cost components to turn it into a high impedance input ADC driver with high voltage capability and error compensation ability. Such a circuit is applicable in instrumentation dedicated to voltage measurement.
