oscillator - Circuitos electrónicos

This circuit is a series of JFET Pierce Crystal Oscillator. JFET Pierce crystal oscillator allows a wide range of crystal frequencies to be used without modification of the circuit. Since the JFET gate did not contain crystals, Q both maintained that insure a good frequency stability

This circuit works much like the classic 555 timer, but draws only about 1.5 microamps from a 3 volt battery. It is highly stable under varying temperature and supply voltages.

This circuit produces an extremely low distortion sine wave, in spite of the non-linear devices used for amplitude limiting (D1 and D2). The reason is first that distortion (harmonics) is fed to the minus input of the opamp with far less loss than to the plus input, severely attenuating them. Circuit designed by Andrew R.
