Abstract:
A multi-bit level-shifter (MBLS) includes two or more input circuits correspondingly configured to operate in a first voltage domain. The MBLS also includes two or more single bit level shifters (SBLSs) electrically coupled correspondingly to the two or more input circuits, and correspondingly configured to operate in a second voltage domain. The MBLS also includes a control circuit configured to toggle each of the two or more SBLSs between a normal mode and a standby mode according to a toggle-control signal received from the control circuit.
