ABSTRACT:
A circuit, includes first, second, and third inverters. The first inverter has a first input coupled to a first port and a first output coupled to a second port. The second inverter has a second input coupled to the second port and a second output coupled to the first port. The third inverter has a third input coupled to the first port through a first capacitor and to a third port. The third inverter has an output coupled to the second port through a second capacitor. The circuit receives a signal having a voltage between a first voltage potential and a second voltage potential and in response outputs a signal having a voltage between the second voltage potential and a third voltage potential. The third voltage potential is higher than the first and second voltage potentials with respect to ground.
