  • Time delay compensation and pulse width correction
    Patent number: 8040181
    Abstract: A system, method and apparatus is provided for pulse width correction in a power driver. In an embodiment, an apparatus includes an operational amplifier having an input and an output. The input of the operational amplifier is coupled to receive an input pulse signal. The apparatus further includes an output stage having an input coupled to the output of the operational amplifier. The output stage also includes a current output configured to couple to a load and to a voltage sense output. The apparatus also includes a comparator having an inverting input coupled to the voltage sense output of the output stage, a non-inverting input configured to couple to an input signal, and an output. Also, the apparatus includes a timing circuit with an input coupled to the output of the comparator and an input coupled to the input signal. The timing circuit also has an output to supply the input pulse signal. The timing circuit measures a delay from a change in the input signal to a change in the output of the comparator.
