[Paul] likes a precise oscillator. His recent video shows a crystal oscillator with a “watch crystal” and a CMOS counter, the CD4060. Using such a circuit can produce very stable frequencies and since ...

Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting output ...

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 ...

The circuit has been designed using a single CMOS integrated circuit of model 4069 to produce a frequency that is twice of the input signal by functioning as a frequency doubler. Frequency – a measure ...

Fig 1. One of the most popular crystal oscillator types is the inverter crystal drive circuit. Fig 2. Shown is the crystal reactance of the third-overtone XO’s third tone. Fig 3. Analog multiplier ...
