Butler oscillator
WebMay 24, 2002 · My contribution was to lift forward the Butler oscillator as an alternative the common Colpitts. A Buttler oscillator is not an alternative for most people since it requires special crystal (series resonance is rather unusual these days). Still, I'm very interested in how a precision oscillator is made (those in a rather large metal can). ••• WebReferring to FIG. 1, there is depicted a Butler oscillator circuit incorporating a crystal X1 connected to a pair of cross coupled field effect transistors Q11 and Q12, each having a load resistor R11, R12 coupled to its drain and a current source CS11, CS12 coupled to …

WebThe advantage of the Butler oscillator is that a small voltage exists across the crystal, reducing stress on the crystal. Fig. 9. Butler oscillator. By replacing the tank-circuit components, the oscillator can be tuned to operate on one of the crystal’s overtone frequencies. RC oscillators use resistance-capacitance networks to determine the ... http://www.butlerautomatic.com/

WebA voltage controlled oscillator operable on two widely separated frequency bands, such as 900MHz and 1.8 GHz for example. The voltage controlled oscillator includes two negative resistance generators (32, 34) which share a common tunable tank circuit (26) and a common impedance matched combiner circuit (28) which provides the RF output (36).
