Abstract :
The paper deals with a crystal oscillator with differential amplifier based on bipolar junction transistors. The main attention is devoted to the influence of loss resistance of the used piezoelectric resonator to the gain at the corresponding open feedback loop. The derived relation for this gain corresponds with relevant results obtained by means of computer simulations.
