Abstract :
This paper presents results from a novel 1 GHz temperature compensated oscillator (TCO) featuring a continuous temperature frequency dependence. This work is a further development of the TCO using combined analogue and digital compensation. The major advantage of the TCO, described here, is that there are no jumps in the temperature frequency dependence which results in a significant improvement of the spectral purity of the output signal. The overall temperature instability is /spl plusmn/1.25 ppm in the temperature range of -30 to +60/spl deg/C.
