This figure is sawtooth wave generating circuit synchronous with industrial frequency power.6-67(a) is awtooth wave generating circuit synchronous with industrial frequency power composed of current mirror.R1 is used to adjust the slope of the waveform.Voltgae two ports of C1 output in original sawtooth wave way so the high impedance circuit is connected. The picture (b) is sawtooth wave generating circuit whose amplitude is constant when the input frequency is changed.R1 and C1 make sawtooth wave smooth, it makes the feedback on the current mirror composed of VT2 and VT3 after A2's comparasion.This circuit fits for industrial frequency,50HZ/60HZ and air or aviation equipment's 400HZ and its corresponding scope is 40 to 400 HZ and its frequency range is very wide.
