Abstract

Device and a method of configuring a voltage level shifter is disclosed. The device includes a traditional level shifter circuit (TLSC), a first control circuit (FCC) cross-coupled to a second control circuit (SCC). The FCC is coupled to receive an inverse of an input at a first input node and provide a first output at a first output node. The SCC is coupled to receive the input at a second input node and provide a second output at a second output node and the TLSC is configured to provide an output at an output node in response to the first output received at the first output node and the second output received at the second output node. A first power source is configured to provide a first power supply voltage to the TLSC, the FCC and the SCC. The output is latched to track the input. The TLSC, the FCC and the SCC are coupled to a ground reference node.
