Abstract

1,191,944. Transistor amplifying circuits. NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY, TRADE & COMMERCE. 1 June, 1967 [3 June, 1966], No. 25342/67. Heading H3T. [Also in Divisions G1 and H1] A differential transistor amplifier is fed by an electrometer tube 18 coupled to ionization chamber 17. Instead of the electrometer, a field-effect transistor may be used. Exemplary circuit values are given.
