ABSTRACT:
An output circuit of a level shifter or an operational amplifier which converts input signal voltages to different voltage levels. A pMOS transistor PT.sub.2 and nMOS transistor NT.sub.2 connected in series between the power source and ground constitute the output node ND.sub.12. A Wilson mirror is made of pMOS transistors PT.sub.3 -PT.sub.6. An nMOS transistor NT.sub.3 induces a current flow in the current mirror, and an nMOS transistor NT.sub.1 connected between the current output node ND.sub.1 of the current mirror and ground. The gate of pMOS transistor PT.sub.2 is connected to the current output node ND.sub.1, and the gates of nMOS transistor NT.sub.1 and nMOS transistors NT.sub.2 and NT.sub.3 are connected to the input line of signals IN and XIN, which are 180.degree. out of phases.
