A Wide-Range Static Current-Free Current Mirror-Based LS With Logic Error Detect

Abstract

We have proposed a current mirror-based level shifter (LS) with a logic error detection (CMLS-LED), which is capable of converting a near-threshold signal to a super-threshold signal. The proposed CMLS-LED resolves the current contention problem observed in the conventional cross-coupled pFET-based LS (CPLS) by using the current mirror and removes the static current in the conventional current mirror LS with adopting the feedback pFET controlled by the output node. Compared with Wilson’s current
