The proposed circuit was experimentally tested using the
AD844 CCII1. The output triangular waveform with
C1 1 mF, and R1 280 V is shown in Fig. 4 along with
the square wave generated at the output of the astable multivibrator.
The frequency of the generated waveforms in this
case is found to be 4.1 kHz. The waveforms frequency can
be changed by varying the values of C1 and/or R1 only. This
will alter the amplitude, however, the amplitude itself can be
adjusted via C2 and/or R3. Throughout this article the
