A wide-range logarithmic electrometer with improved accuracy and temperature stability

A seven-decade temperature-compensated logarithmic electrometer is presented. Temperature compensation is achieved by using an array of four matched monolithic bipolar transistors and straightforward postprocessing techniques. Use of this method results in
