Crystal oscillation circuit
WebAug 25, 2024 · A Pierce oscillator is built around a crystal (X) and load capacitors (C 1 and C 2 ), wrapped with an inverting amplifier using an internal feedback resistor. Under the right conditions, when the output of the amplifier is fed back into the input, it results in a negative resistance and oscillation occurs. WebA crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. The oscillator frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.The most common type of …
