Abstract

A level shifting circuit including a driving circuit, a reset circuit, a coupling circuit and an output-stage circuit is provided. The driving circuit, controlled by the input signal, controls the first driving signal having a high voltage level in the first period and controls the first driving signal having a low reference level in the second period. The reset circuit, controlled by the first driving signal in the first period, resets the second driving signal having the low reference level. The coupling circuit, controlled by the falling edge of the input-inversed signal, controls the second driving signal having a low voltage coupling level in the second period. The output-stage circuit, controlled by the first and the second driving signal, controls the output signal having a high voltage level in the second period and controls the output signal having a low voltage level in the first period.
