Abstract
A semiconductor device includes a differential amplifier and a first and a second pull-up transistor for generating a reference voltage. The second pull-up transistor has a gate connected to an output terminal of the differential amplifier. The differential amplifier is such that, when an output voltage thereof previously outputted is at a high level, both the first and second pull-up transistors become conductive so that the reference voltage becomes equilibrium at a high level voltage, and when an output voltage previously outputted is at a low level, the first pull-up transistor becomes conductive and the second pull-up transistor becomes non conductive so that the reference voltage becomes equilibrium at a low level voltage. With this arrangement, a high speed operation of the differential amplifier is realized.
