Abstract
Provided is a pulse modulation circuit capable of generating a pulse modulation signal with a steep rise and a desired pulse width at a desired timing not depending on a transmission signal sequence. In this circuit, a control signal generation unit () generates a first control signal if transmission data (S) is '1' and a second control signal if the transmission data (S) is '0.' The control signal generation unit () controls an oscillator () of an intermittently operating circuit () to be at an oscillation state for outputting a desired first oscillation signal while the first control signal is turned ON and controls the oscillator () to be at an idling state for outputting a second oscillation signal having a lower amplitude than the first oscillation signal while the second control signal is turned ON.
