JFET Pierce Crystal oscillator | Electronic Circuit Schematic

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

Wien Bridge Oscillator

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) are fed to the minus input of the opamp with far less loss than to the plus input, severely attenuating them. Second, a Wien bridge oscillator requires a gain of exactly 3.00. No more and no less. For lowest distortion, calculate the minimum and maximum available gain to just above and just below 3.00. In other wo.......
