Patent ID: 7161405

Claim:
A level shift circuit for amplifying an input signal having a first amplitude to an output signal having a second amplitude, comprising: a first inverter having a first input terminal and a generating the output signal, the first inverter including a first transistor having a first current driving capacity; a second inverter having a second input terminal connected to the first output terminal and a second output terminal connected to the first input terminal, the second inverter including a second transistor having a second current driving capacity that is smaller than the first current driving capacity; and an inversion circuit having a third output terminal connected to the first input terminal, the inversion circuit receiving the input signal including a first input signal and a second input signal, the inversion circuit including a third transistor having a third current driving capacity that is smaller than the first current driving capacity and is larger than the second driving capacity, wherein one of the first and second input signals is a one-shot pulse signal.
