Patent attributes
An object is to provide a driver circuit as well as a level converting circuit, capable of reducing current consumption and accelerating an operation, and in the driver circuit that changes a voltage level of an output signal in correspondence with a change in voltage level of an input signal, when a transistor is turned on and a voltage level of an output signal changes, a positive feedback operation of raising a voltage of an output node of an input stage circuit that drives the transistor is performed, whereby a gate-source voltage of the transistor increases while an on-resistance thereof decreases, and a change in voltage level of the output node in the positive feedback operation is accelerated due to a bootstrap action in the input stage circuit.
