Abstract: PURPOSE: To provide a circuit and method for converting small-amplitude signals into total-amplitude signals which can be realized in a single battery driving state and in an integrated circuit without using any electric power during static operation. CONSTITUTION: A signal receiving circuit 20 which converts small-amplitude signals into total-amplitude signals is incorporated with an input stage 22 which generates intermediate signals in response to the small-amplitude signals and first and second control signals, an output stage 28 which generates the total- amplitude signals in response to the intermediate signals, and first and second feedback stages 24 and 26 which respectively couple the first and second control signals with the input stage 22 in response to the total-amplitude signals. The feedback stages 24 and 26 respectively have first and second power terminals 38 and 44 and the output stage 28 has third and fourth power terminals 52 and 54.  Since the CMOS transistor constituting each of the above-mentioned stages has an appropriately selected turning-on threshold and makes 'full' turning-on or complete turning-off in response to a related signal, static power dissipation hardly occurs or does not occur in the circuit 20.
