ABSTRACT:
A triangular waveform is generated by alternately charging and discharging a capacitor through two voltage-controlled current sources. A single tuning amplifier and a variable impedance, coupled to the voltage-controlled current sources, allow the symmetry of the triangular waveform to be varied while a constant repetition rate is maintained.
