Zero-transient switching of a subharmonic parametric oscillator

An analytical technique is presented for the determination of the time variation of the current necessary to switch phases of a subharmonic parametric oscillator within one cycle of the output voltage and with zero transient. An approximation to the required switching current is generated by a suitable shaping circuit, and the validity of the analysis is confirmed by practical observation. Using such switching techniques, the oscillator, which uses the diffusion capacitance of a junction diode, might be used to represent the binary variable and might have faster switching times than existing parametric computing elements.
