The Pierce oscillator is a type of electronic oscillator particularly well-suited for use in piezoelectric crystal oscillator circuits. Named for its inventor, George W. Pierce (1872–1956), [ 1 ] [ 2 ] the Pierce oscillator is a derivative of the Colpitts oscillator .
G. W. Pierce had an eye for finding the main sticking point in physical processes. For electronics, he saw that resonance was a key phenomenon. His five-part series "Experiments on resonance in wireless telegraph circuits in Physical Review (1904-7) are evidence of his leadership.
Simple relaxation oscillator made by feeding back an inverting Schmitt trigger's output voltage through a RC network to its input.. An electronic oscillator is an electronic circuit that produces a periodic, oscillating or alternating current (AC) signal, usually a sine wave, square wave or a triangle wave, [1] [2] [3] powered by a direct current (DC) source.
The above analysis also describes the behavior of the Pierce oscillator. The Pierce oscillator, with two capacitors and one inductor, is equivalent to the Colpitts oscillator. [8] Equivalence can be shown by choosing the junction of the two capacitors as the ground point. An electrical dual of the standard Pierce oscillator using two inductors ...

There is often misunderstanding around Leeson's equation, even in text books. In the 1966 paper, Leeson stated correctly that "P s is the signal level at the oscillator active element input" (often referred to as the power through the resonator now, strictly speaking it is the available power at the amplifier input).
