Crystal Controlled Oscillator Circuit Diagram. The circuit in fig. Crystal oscillator circuit diagram 1 as shown in the figure it is a simple crystal oscillator circuit composed of three gates of a1 four resistors tuning capacitors and a crystal.
Oscillator loop gain 19 4 4. Has been experimented with by the author on the range 1 mhz to 18mhz and will be encouraged. Dc biasing of transistor and ic amplifier stages 21 4 6.
This frequency is often used to keep track of time as in quartz wristwatches to provide a stable clock signal for digital integrated circuits and to stabilize frequencies for radio transmitters.
Almost any crystal in the 1 to 15 mhz range can be used. Has been experimented with by the author on the range 1 mhz to 18mhz and will be encouraged. The basic components used in the circuit inductance l represents crystal mass capacitance c2 represents compliance and c1 is used to represent the capacitance that is formed because of crystal s mechanical moulding resistance r represents the crystal s internal structure friction the quartz crystal oscillator circuit diagram consists of two resonances such as series and parallel resonance i e two resonant frequencies. The crystal usually quartz has a high degree of stability in holding con stant at whatever frequency the crystal is originally cut to operate.
