Abstract : The purpose of this program was to advance circuit techniques for a new class of ovenless crystal oscillators having frequency temperature stabilities previously achieved in temperature stabilized oscillators consuming several watts of power. Two basic approaches to obtain computer optimized component values for a compensation network required to generate a desired non-linear voltage function, and hence achieve the desired degree of stability, are presented. Two groups of oscillator units, one group built to achieve a design goal frequency stability of + or -1 x 10 to the minus 7th power over the ambient temperature range of -40 C to +75 C and the other group built to achieve a design goal frequency stability of + or -5 x 10 to the minus 8th power over the ambient temperature range of -5 C to approximately +85 C, are discussed.
