A crystal oscillator circuit is disclosed including a differential amplifier, a positive feedback assembly, and a series resonant crystal assembly. The differential amplifier includes a first transistor and a second transistor. The positive feedback assembly is coupled to each of the first and second transistors, and has a loop gain of greater than unity. The series resonant crystal assembly is coupled to one of the first and second transistors, and includes a crystal and a capacitor.
