Abstract :
A digital oscillator having a unique limit cycle, independent of the initial conditions, is described. The oscillator is synthesized by discretizing a continuous oscillatory system described by a nonlinear difference-differential equation. Simulation results for a system utilizing a word length ranging from 8 to 12 b are in good agreement with analytical results.
