Abstract
Techniques are described for providing, in a gate driver circuit, a compensation current to compensate for parasitic displacement current induced during the rising edge of an output voltage at an output gate of the gate driver circuit. In one example, the techniques of the disclosure include activating, by a bridge driver circuit for a direct-current (DC) motor, a driver of the bridge driver circuit and measuring, by the bridge driver circuit, a parasitic current of the driver during a rise time of an output gate voltage of the driver. In response to the measured parasitic current, generating, by the bridge driver circuit, a compensation current; and outputting, by the bridge driver circuit and to the output gate of the of the driver, the compensation current.
