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.
Electronic oscillation is a repeating cyclical variation in voltage or current in an electrical circuit, resulting in a periodic waveform. [1] The frequency of the oscillation in hertz is the number of times the cycle repeats per second. The recurrence may be in the form of a varying voltage or a varying current.
A clock generator is an electronic oscillator that produces a clock signal for use in synchronizing a circuit's operation. The output clock signal can range from a simple symmetrical square wave to more complex arrangements. The basic parts that all clock generators share are a resonant circuit and an amplifier.
A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. [1] [2] [3] 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.
crystal oscillator An electronic oscillator whose frequency is stabilized by a piezoelectric crystal resonator element. Ćuk converter One kind of buck-boost voltage converter that uses a capacitor as an energy storage element. current The movement of electric charge. current density The current flowing per unit area of a conductor. current ...
Clock signal and legend. In electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat) [1] is an electronic logic signal (voltage or current) which oscillates between a high and a low state at a constant frequency and is used like a metronome to synchronize actions of digital circuits.
