Gives high input impedance and low drift at low cost, with approximately unity gain. Uses one fet and three bipolar transistors. Suitable for d-c voltmeter having 0.1 v full scale on lowest range. Temperature drift is low.-J. M. Colwell, Direct-Coupled Amplifier Cuts Cost of D-C Voltmeter, Electronics, 39:12, p 109-110.
