The Synthesis of Integrable, Nearly Sinusoidal, Potentially Bistable Oscillators

A procedure is given for the synthesis of a class of potentially bistable oscillator configurations which serve as proto-types for integrated, nearly sinusoidal applications. These oscillator configurations are synthesized by systematic addition of one- and two-port resistor-capacitor networks to integrable bistable circuits having two 3-terminal, charge-controlled, active devices. The procedure is based on the synthesis and embedding of open-circuit stable negative-resistance ports. The oscillators synthesized are conveniently classed as 2-, 3-, or 4-terminal oscillators and typical performance characteristics of lumped prototype and integrated realizations are given. Configuration synthesis is shown to enable the specification of properties which determine the ease of integrated realization (for example the nonisolated active device property).
