  • Patent number: 8169193
    Abstract: A circuit for dissipating injected parasitic charge includes a circuit stage, a pulse generating circuit and a switch. The circuit stage has an input node and an output node that injects a parasitic charge when switched OFF to the output node. The pulse generating circuit can generate a pulsed signal having an input for receiving a control signal. The control signal indicates the circuit stage is switching OFF, and has an output for outputting a pulsed signal in response to the control signal at the input. The pulsed signal can have a predetermined duration. The switch can be configured to be actuated by the pulsed signal output by the pulse generating circuit, and has a terminal connected to the output node of the circuit stage and a terminal connected to circuit to substantially dissipate the injected parasitic charge.
