Abstract
A level shift circuit includes an input stage and an output stage coupled to each other by two nodes. The input stage changes the voltages on the nodes according to an input signal, and the output stage determines an output signal according to the voltages on the two nodes. In a transition state, the input stage provides a large current to charge or discharge the first node or the second node so as to quickly change the voltage thereon. In a steady state, the input stage lowers the current so as to reduce power consumption.
