ABSTRACT:
The semiconductor device includes a first current mirror circuit combining analog power sources and digital power sources to receive small amplitude signals and constant-voltage input signals, a second current mirror circuit for receiving a signal output from the first current mirror circuit and for level-converting the signal from analog power source to digital power source, a first node provided in the first current mirror circuit, a second node provided in the second current mirror circuit, and an inverter circuit for receiving a signal output on the basis of the voltage levels of the first node and the second node and for outputting a CMOS level signal.
