A simple oscillator circuit is described in which, by means of impedance transformation, the tube impedances are made small relative to those of the tuned circuit. As a result all frequency variations inherent in the tube are reduced by a factor of ten, or more. The method is applicable to oscillators throughout the range from audio to ultra-high frequencies.

An L-C oscillator having unusual frequency stability is described and briefly analyzed. The circuit is similar to the familiar Colpitts, with an L-C series circuit replacing the inductor. Such a… Expand

A simple theory of the conditions for oscillation, and of the frequency stability of inductance-capacitance oscillators is evolved from a survey of a number of papers on this subject. As some of… Expand

It is a well-known fact that negative feedback has a favorable influence on the phase stability of an amplifier. However, if the negative feedback is applied between the input and output terminals of… Expand

This thesis deals with fully integrated LC oscillators and local oscillator (LO) signal generation circuits. In communication systems a good-quality LO signal for upand down-conversion in… Expand

A constant frequency oscillator, which depends for its operation upon the use of electron coupling between the oscillation generating portion of the circuit and the work circuit, is described. This… Expand

The frequency of an oscillator operating just on the threshold of the oscillation generation is determined-as is well known-by the constants of the circuit only; i.e., it does not depend on the… Expand
