Abstract
A simple circuit scheme, able to generate square/triangular wave, is proposed. Its advantages are that oscillation frequency and amplitudes of the proposed circuit do have a small range of temperature drift. Electronic adjustments of them can be obtained with a wide sweep range and DC offset adjustment available. In addition, the proposed scheme can produce frequency-constant derivative of PWM signal without an additional device requirement. It is very appropriate for, with simple circuit details, not only circuit implementation but also monolithic fabrication. The PSPICE simulation results through bipolar technology are given here, they show good performance of the proposed circuit.
