CURRENT_SUMMING_OPERAIIONAL_AMPLIFIER

Published:2009/7/14 21:12:00 Author:May | From:SeekIC

Uses current-summing to hold voltage at input node R1 at 0V. With more than one input, there is exact summation of inputs, with no interaction. As sine-wave amplifier, gain is 1,000, and bandwidth for transistors shown is d-c to 20kc.-C. J. Ulrick, Minimum. Interaction Summing Amplifier, EEE, 12:2, p 30.
