SINE_COSINE_OSCILLATOR

Two oscillators in cascade with positive feedback generate two sine waves in quadrature (differing in phase by 90°). Limiting network D1-D2-R5 is used around A2 to prevent oscillator from stabilizing at saturation limit of A2. R5 is used to set output at any level above zener limits of D1-D2. Frequency is 1 kHz for values shown.-W. G. Jung, IC Op-Amp Cookbook, Howard W. Sams, Indianapolis, IN, 1974, p 371-372.
