Abstract
Techniques are disclosed relating to level-shifting circuitry and time borrowing across voltage domains. In disclosed embodiments, an apparatus includes pulse circuitry, latch circuitry, pull circuitry, and feedback circuitry. The pulse circuitry is configured to generate a pulse signal in response to an active clock edge. The latch circuitry is configured to store a value of an input signal, where the input signal has a first voltage level. The pull circuitry is configured to drive, during the pulse signal, an output of the latch circuitry to match a logical value of the input signal at a second, different voltage level. This may allow the input signal to change during the pulse, enabling time borrowing. The feedback circuitry is configured to maintain the output of the latch circuitry at the second voltage level after the pulse signal.
