Questions tagged [compensation]
For questions about designing electronics to account for undesirable characteristics or behaviors, such as frequency compensation in a feedback control system to avoid instability and/or improve gain and phase margin, reduce overshoot and ringing, improve bandwidth, etc. Consider using in conjunction with associated tags such as "feedback", "stability", "frequency-response", "nyquist-plot", "bode-plot", "operational-amplifier", etc., if appropriate.

Is it OK to use the inverting input of the opamp as reference input?
In order to measure negative current without a negative supply, I mix the current sense signal with the positive reference. Now, when the current increases, the control signal decreases. To stabilize ...
