Switch-Controllable OTRA-Based Square/Triangular Waveform Generator

摘要

A switch-controllable square/triangular waveform generator is presented. The circuit consists mainly of two operational transresistance amplifiers and three switches. The dc level of the triangular signal can be adjusted. Both inverting and noninverting mode operations can be fulfilled. A prototype circuit is implemented and experimental results are recorded to demonstrate its feasibility.
