1. A shift resistor circuit, comprising:
- an OR-gate unit for receiving a start pulse or an output of a previous stage and a feedback signal;
a level shift unit for level-shifting a swing voltage of a clock signal in response to an output signal of the OR-gate unit; and
a buffer for transferring an output of the level shift unit to a next stage as an input signal.

Abstract
A shit resistor circuit and a method of operating the same are disclosed. The shift resistor circuit includes an OR-gate unit for receiving a start pulse or an output of a previous stage and a feedback signal; a level shift unit for level-shifting a swing voltage of a clock signal in response to an output signal of the OR-gate unit; and a buffer for transferring an output of the level shift unit to a next stage as an input signal.
