ABSTRACT
Describes a battery-powered head-amplifier resolving 0.025 pA, which uses active compensation to substantially cancel the interference, allowing the atmospheric charge fluxes to be resolved in the presence of the interference. Overall response; Ability of the head amplifier to drive a low impedance line; Schematic of the filtered amplifier system.
