Abstract
A "starved operation" d.c. amplifier is described, having a drift of less than 100 [mu]V in 30 min., grid current less than 10-11 A and a noise level referred to the input of 15[mu]V with 10 M [OMEGA] grid resistors. Circuits are also described for using the amplifier with commercial cathode-ray and pen oscillographs.This publication has 1 reference indexed in Scilit:
