Patent ID: 8018266

Claim:
A level shifting circuit generating an output signal according to an input signal and an input-inversed signal, wherein the level shifting circuit comprises: a driving circuit, comprising a first inverter having a first output end, the driving circuit controlled by the input signal to produce a first driving signal having a high voltage level from the first output end in a first period, and produce the first driving signal having a low reference level from the first output end in a second period; a reset circuit having an output node for generating a second driving signal, the reset circuit controlled by the first driving signal to reset the second driving signal having the low reference level in the first period; a coupling circuit controlled by the falling edge of the input-inversed signal to control the second driving signal, so that the second driving signal has a low voltage coupling level in the second period; and an output-stage circuit, comprising a second inverter having a second output end, the output-stage circuit controlled by the first and the second driving signals to produce the output signal having the high voltage level from the second output end in the second period and produce the output signal having a low voltage level from the second output end in the first period.
