A very simple DIY crystal oscillator circuit which use a quartz for frequency stability and a good rf transistor. Use a 2-nd or 3-rd harmonic crystal, for example if you want 100MHz use a 50MHz or ...
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 ...
Fig 1. This Pierce-series resonant oscillator can reliably start at supply voltages as low as 2.4 V. It also draws very low current, ensuring long battery life. Fig 2. An oscilloscope photo shows the ...
