1. A current-limited oscillator, comprising:

  • a delay section that includes a plurality of series-connected inverters to delay an output pulse on the basis of a current limiting level indication signal;

    at least one first transistor that limits a first current between said inverters and a high potential power supply; and

    at least one second transistor that limits a second current between said inverters and a low potential power supply, wherein at least one of said plurality of inverters is configured as a first inverter that is connected with said first transistor and is not connected with said second transistor, and at least another of said plurality of inverters is configured as a second inverter that is not connected with said first transistor and is connected with said second transistor.
