TEMPERATURE_COMPENSATION_IN_EGG_AMP

Circuit has common-mode rejection ratio of 10,000, with adjustable cancellation of unbalanced noise at input, for electrocardiograph. For temperature compensation, C3 bypasses ac signals from base of Q7, so only d-c signals are fed back through this transistor to Q1.-J. R. Smith, Jr., Amplifier Can be Adjusted to Cancel Unbalanced Noise, Electronics, 37:23, p 60-61.
