<p><P>PROBLEM TO BE SOLVED: To provide a sawtooth wave generation circuit, capable of generating a desired voltage waveform without having to use an expensive power amplifier. <P>SOLUTION: The sawtooth wave generation circuit includes: a bias means for setting a final voltage value of a sawtooth wave voltage during a discharge process; a constant-current means for outputting the constant current of a set predetermined value; a charge means for performing charge by current outputted from the constant current means; and a control means for controlling the output voltage of the charge means to a sawtooth wave voltage, by performing charge and discharge of the charge means and for controlling the inclination of the output waveform, output voltage value and cycle. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
