Abstract: PURPOSE:To modulate the amplitude of a digital signal to be inputted by means of simple circuit constitution by formed a circuit by means of a MOS type field effect transistor (MOSFET), a capacitor and a control circuit and modulating the amplitude of the signal which is inputted to MOSFET. CONSTITUTION:Firstly, the gate voltage of MOSFET1 is set to a ground potential. When a clock signal CK1 is the ground potential, a P type MOSFET 7 comes to a conductive state and the capacitor 8 is charged to a power potential Vcc. A charge which is charged in the capacitor 8 is divided into the capacitors 5 and 8. The gate voltage of MOSFET1 rises in correspondence with charge quantity which is moved to the capacitor 5. Above action is repeated and the gate voltage of MOSFET1 sequentially rises at every period of CK1. An output signal Sout outputted from a signal output part 3 with the rise turns into a signal having an amplitude obtained by modulating the amplitude of an input signal Sin in correspondence with the rise of the gate voltage.
