Patent ID: 7397234

Claim:
A current sensor for sensing a first current, comprising: an integrator for providing an output signal responsive to an induced current corresponding to the first current; and a reset circuit coupled to receive a control signal and to supply a reset signal to reset the integrator in response to the control signal, the reset signal, when asserted, coupled to cause the integrator to be in a reset state for a time period shorter than an assertion time of the control signal; and wherein the reset circuit includes a one-shot circuit and one or more logic gates and wherein the one-shot circuit includes an input and an output and the one or more logic gates includes a first input, a second input and an output, and wherein the input of the one-shot circuit and the first input of the one or more logic gates receive the control signal and the output of the one-shot circuit is coupled to the second input of the one or more logic gates, where the output of the one or more logic gates provides the reset signal whose pulse width is less than a pulse width of the control signal.
