Circuit Graph
Single-supply voltage-controlled oscillator using 555 Timer, Op-Amp, and NPN BJT. The 555 timer functions only as inverting comparator with hysteresis. The output signals are square, triangular, and exponential waveforms. Rxpchg, Rxpdch, and Cxpl determines the rise and decay times of the exponential output waveform.
