Title:
三角波生成回路
Document Type and Number:
Japanese Patent JP4684112
Kind Code:
B2
Abstract:
An accurate intermittent triangular wave signal without waveform distortion is generated by a triangular wave generation circuit 1 including a rectangular wave generation circuit 111 for generating an intermittent rectangular wave signal in which a rectangular wave interval and a direct current interval of a predetermined level are repeated; an integration circuit 12 for generating an intermittent triangular wave signal in which a triangular wave interval and a direct current interval are repeated based on a reference signal and the intermittent rectangular wave signal generated by the rectangular wave generation circuit 111; and a triangular wave correcting circuit 112 for correcting waveform distortion of the intermittent triangular wave signal based on a differential voltage between a starting point and an ending point of the direct current interval of the intermittent triangular wave signal output from the integration circuit 12.
