Abstract
This paper describes a fast response picoammeter design incorporating a commercially available transistorized differential amplifier. The input circuit uses three transistors and one electrometer tube and has unique features. A guard signal is provided for the reduction of input cable capacitance. Problems associated with large range resistances are discussed.Keywords
