OSCILLATOR USING SCHMITT TRIGGER CIRCUIT

摘要

Provided is an oscillator using a Schmitt trigger circuit, the oscillator including a constant current generating section that generates a current with a constant magnitude; a current mirroring section that is connected to the constant current generating section and mirrors the current generated by the constant current generating section; a control section that is connected to the current mirroring section and supplies or blocks the current applied through the current mirroring section; a capacitor of which one end is connected to the control section and the other end is grounded, the capacitor being charged with a current supplied by the control section; a Schmitt trigger circuit that receives the voltage charged in the capacitor so as to output a high- or low-level voltage; and a voltage delay section that is connected to the Schmitt trigger circuit and delays the voltage output by the Schmitt trigger circuit to output.
