Ternary Parametron Based on Subharmonic Oscillation of Order Three by Forcing

To realize a phasor based ternary logic, a sub-harmonic oscillator of order three by forcing excitation is needed. It is known that for sinusoidal forcing, a forcing period exactly one-third of the free period is impossible. To overcome this difficulty, an oscillation amplitude dependent forcing is proposed. In this paper using numerical simulation, a stable oscillation and a phase control by seed signals are shown.
