摘要
Output signal generation circuitry 100 may be used for converting an input signal 110 from 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 circuitry 160 operating from the supply voltage, which is configured to generate at an output node 130 the output signal for the destination voltage domain in dependence on the input signal. The output signal generation circuitry may also comprise tracking circuitry 280A, 280B, 280C, 280D 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 circuitry 180A, 180B 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.
