Fundamental oscillators based on diamond transistors

This paper brings complete list of the simplest network structures capable to generate harmonic signals. The core elements used are modern analog building blocks known as the diamond transistors. Utilized design procedure is based on the prescribed state space representation of the second-order oscillators such that the final circuits contain minimum amount of the components and its basic frequency can be electronically adjusted. Each oscillator has been analyzed numerically, verified by the Pspice simulations as well as validated experimentally. The selected results of some importance are included. Since the nonlinear higher-order complex motions have been recognized during the measurement this behavior is briefly discussed.
