A level shift circuit for conversion of a low-voltage input signal into a high-voltage output signal is provided. The level shift circuit includes: two pairs of transistors, a control unit, and a charge-sharing unit. The transistors in one of the pairs are both turned on in response to the input signal so that a voltage on a reference voltage node is coupled to a gate of one of the transistors in the other pair. A control unit decouples and couples a first reference voltage from the reference voltage node during a first and second phases respectively. A charge-sharing unit is temporarily shorting for preventing failure of conversion.
