Title:
Level shift circuit
Abstract:
The present invention discloses a level shift circuit and a control pulse shaping unit therewith. A level shift circuit for transition of a low-voltage input signal into a high-voltage output signal, the circuit comprising two pairs of transistors and a control unit. Two pairs of transistors, wherein 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 decoupling a reference voltage from the reference voltage node during a first phase, and partially and fully coupling the reference voltage to the reference voltage node respectively during a second and third phases.
