Abstract
An electronic clamp is provided for an integrated circuit having a first voltage island () to which an output signal (clamp out) of the clamp is applied and a second voltage island () operative to produce an input signal (clamp in) to the clamp, where power to the second voltage island can be switched off to save power. The clamp comprises a latch () which stores or retains the clamp value (or) of the input signal (clamp in) during a reset period and clamps the output signal (clamp out) to the stored or retained value in response to a clamp enable signal, (clamp in) in order to protect the first voltage island from a non-stabilised input signal.
