ELECTRICAL STIMULATION FOR A FUNCTIONAL ELECTRICAL STIMULATION SYSTEM

An electrical stimulation system and method for generating a stimulation signal for at least two electrodes coupled to a body part in a functional electrical stimulation system. One example embodiment includes a controller unit operable for receiving stimulation parameters and a trigger signal, and in response to receiving the trigger signal, outputting control signals based on the stimulation parameters. A voltage conversion module coupled to the unit receives the control signals and converts a supply voltage based on the received control signals. A switch receives the converted supply voltage at a first terminal and outputs a simulation signal at a second terminal. Outputting of the converted supply voltage at the second terminal by the switch is controlled by a driver module based on the received control signals.
