Abstract
A level shifter ( ) that may provide a relatively high-speed operation in a level shifting mode and a non-level shifting mode has been disclosed. Level shifter ( ) may include a transistor (P ) providing a controllable current path between a voltage terminal ( ) and an output signal (TOUT) based on the logic level of an input signal (IN). Series connected transistors (P and P ) may provide a controllable current path between voltage terminal ( ) and output signal (TOUT) based on the logic level of an input signal (IN). Transistor (P ) may be enabled in a Vcc mode and may be disabled in a Vpp mode. In this way, an equivalent transistor width (WT) may be adjusted in accordance with a mode of operation and a transition time of output signal (TOUT) may be improved.
