Capacitor C2 charges up to the oscillator when the 4066 switch closes, and holds when it’s open. For now, the time that the circuit samples (the button switch is closed) is the same as the ...

Traditionally, tuning RF oscillator circuits has been a function of an adjustable capacitor. But capacitance is only part of the circuit, with inductance being the other important portion.

To provide this flexible solution, during the design phase, an exploration of the design space is carried out for the chosen circuit architecture, in this case a ring oscillator. Within the boundaries ...

The oscillator circuit is designed to drive a parallel resonance AT cut crystal with a certain drive level; this drive level is dependent by the ESR parameter. If a crystal is specified for a lower ...

Mike Wyatt uses the built-in Bode function of modern DSOs to investigate a Peltz oscillator with injection locking.
