Pierce Crystal Oscillator Design - The Pierce oscillator....is essentially a
common emitter amplifier with a tuned circuit for a collector load and a quartz
crystal as a feedback element. In order to determine whether the Barkhausen criteria
is satisfied, loop gain must be determined at the frequency of oscillation. This
is accomplished by drawing the AC equivalent circuit of the Pierce
Oscillator....(added 02/05) |

Ultra Low Power 32kHz Crystal Oscillator - I have used this circuit many
times when I needed a low frequency reference, which did not draw much power.
With the components show, the current from a 3v battery is less than 1.2 microamps.

Very Low Power Gated Crystal Oscillator - The circuit gates the output of a
continuously operating 32KHz crystal oscillator to the input of a C-MOS buffer when
clock pulses are needed. The technique gets around the problem of a slow starting
crystal oscillator by keeping the oscillator going and switching on a transistor power
stage only as needed. The method keeps the standby power consumption to a very low 1uA
when used with a 3v supply. …. [Designed by David A. Johnson] |

XTAL-Controlled FM TX (V6) - My FM Wireless microphone V5 has been very
popular, both as a beginners project and as a kit. It is interesting that it has also
been the biggest cause of lots of e-mail, the most common question being How can I
make it crystal controlled?. The oscillator can be made crystal controlled; replace
the 2p7 with a 5th harmonic crystal. The oscillator will then be very stable, so
stable in fact, that it cannot even be modulated!This means that you could only use it
to send CW (morse code).... [from Harry Lythall's website] |
