Have you ever wondered how a clock signal that ticks once every few nanoseconds is generated? A billion times a second clock would indeed be an impossible feat a hundred years ago. But, you'd be surprised to find that the clock inside your smartphone is rather identical to an analog wall clock that ticks through the seconds, minutes, and hours of the day. In this video, we explore an analog clock's gear train, the quartz crystal oscillator, the feedback loops for this oscillator, and then how a gigahertz signal is produced using a phase-locked loop.
