Default Oscillator stable frequency to the temperature using MOSFET and Crystal Quartz

This circuit is a Oscillator with frequency stable, use a un MOSFET N-
channel enhancement mode vertical D-MOS transistor (BS108), a Crystal
quartz a 24MHz, is a Oscillator a low cost and
stable frequency to the temperature. Util for applications AM and FM.
