Abstract
Output signal generation circuitrymay be used for converting an input signalfrom a source voltage domain to an output signal for a destination voltage domain, the destination voltage domain operating from a supply voltage that exceeds a stressing threshold of components within the output signal generation circuitry. The output signal generation circuitry may comprise level shifting circuitryoperating from the supply voltage, which is configured to generate at an output nodethe output signal for the destination voltage domain in dependence on the input signal. The output signal generation circuitry may also comprise tracking circuitryA,B,C,D associated with at least one component of the level shifting circuitry to ensure that a voltage drop across the at least one component does not exceed the stressing threshold, wherein the tracking circuitry additionally introduces a delay in a change in the output signal in response to a change in the input signal. Timing compensation circuitryA,B may also be provided, to control the voltage on the output node in a manner to compensate for the delay introduced by the tracking circuitry.
