Level-shifters are an indispensable circuit in multi-power-domain SoCs. Many techniques and architectures have been proposed to enhance the performance of these circuits. Inverter-based level shifters ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...
