Today, the majority of electronic circuits (including microprocessors, microcontrollers, FPGAs, and CPLDs) are based on clocked logic, requiring a timing source. Depending on the frequency accuracy ...

Examine a traditional Hartley oscillator circuit, and you’ll note its trademark: a tapped inductor that determines the frequency of oscillation and provides oscillation-sustaining feedback. Although ...

Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...

The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure 2 depicts the typical timing ...
