500_MEG_D_C_INPUT_RESISTANCE

Published:2009/7/15 2:45:00 Author:Jessie | From:SeekIC

Bootstrap-collector circuit uses starved transistor to provide 500-meg d-c input resistance with 100-v input signal. A-c resistance is even higher, in the 1,000-megohm region at low audio frequencies.-B. M.Bramson, Starved Transistors Raise D-C Input Resistance, Electronics, 32:5, p 54-55.
