In the figure is a triangular wave generating circuit whose amplitude adjustment precision is ±0.01V. If a DC voltage is imposed on V+REF and V-REF, their amplitudes of the triangular wave are the peak the values of V+REF and V-REF, respectively. This circuit combines the integrator and two comparators which is used to judge the positive and passive peaks. If the output of the comparator on the positive terminal is positive, DI is locking on its own, and the output of the comparator on the passive peak is passive. If R1 was the potentiometer, the frequency would be changed and the amplitude is maintained.
