Abstract
An apparatus to monitor and control a switching rate in a switch includes a differentiator circuit including a capacitor and a configurable resistor. The differentiator circuit further includes an input terminal of the capacitors configured to receive a first voltage from a switch and a differentiator node configured to receive a differentiated voltage based on the first voltage. The apparatus includes a peak detector circuit coupled to the differentiator node and configured to detect a peak value of the differentiated voltage. The apparatus further includes a driver circuit coupled to the peak detector circuit and configured to adjust a control signal to the switch responsive to the detected peak value of the differentiated voltage.
