TRIANGULAR WAVEFORM GENERATOR AND METHOD FOR GENERATING TRIANGULAR WAVEFORM THEREOF

摘要

PURPOSE: A triangular waveform generator capable of regulating the pulse width of triangular waves for having various duty ratios and a triangular wave generation method thereof are provided to minimize the number of elements necessary for triangular wave generation, thereby simplifying a total structure. CONSTITUTION: A square wave signal generator(110) generates a square wave signal for the generation of triangular waves. A triangular wave generator(100) is able to generate the square wave signal in response to a reset signal. A resistance unit(120) is connected between the square wave signal generator and a capacitor unit(130). The resistance unit is able to control the voltage level of the square wave signal. The capacitor unit generates a triangular wave signal by using the square wave signal. The capacitor unit includes variable capacitors. The capacitor unit receives the square wave signal outputted from a transistor connected to an output terminal.
