Original Abstract

This paper introduces novel solution of triangular and square wave generator employing circuitry of interesting and unusual Schmitt trigger and specially prepared modification of lossless integrator connected in low-impedance input terminal of the comparator that allows linear charging of capacity and therefore also triangular wave generation that is not available in standard cases of applications (only relaxation generator available – exponential and square wave). Design and supposed operation of the circuit was verified not only theoretically but also experimentally with CMOS implementation of employed active elements available in form of IC device fabricated in 0.35 μm I3T ON Semiconductor process. Achieved result confirmed studied features of triangular wave generation and linear electronic tunability of its frequency between 23 and 151 kHz.
