RC-Transistor Chaotic Circuit using Phase Shift Oscillators with variable capacitance and its frequency performance. This series of arti-Noise in oscillators can be cles discusses oscil-controlled by proper lator phase noise choice of the resonator, reduction techniques and supported by circuit d... ...
The Phaseshift Oscillator is characterised by 3 high-pass filters, creating a 180° phase shift. The output is a sinewave. Take care not to load the output - this will prevent reliable start-up and may stop the circuit from oscillating. Reduced the 3k3 load resistor if the load preve...
Effects of gamma radiation on a transistor RC phase-shift oscillator An investigation was conducted of a transistor RC phaseshift oscillator in operation in a 1000-curie Co/sup 6//sup 0/ gammaray environment. A total of seve... WM Locke,VW Moore 被引量: 1发表: 1960年 The Transistor Ampl...
Basic theory tells us that gain and phase shift are required to build an oscillator. Unfortunately, feedback systems, such as operational amplifiers, have gain and phase shift. The close relationship between oscillators and feedback amplifiers requires careful attention when an op amp is designed. ...

Thanks a lot Jony130!(A practical problem I've had recently, was that I wanted to control the frequency of a (phase shift op amp based) oscillator. I can change it with simple potentiometer, or a digital pot via SPI, but I don't know how to do a similar thing in an analog way ...

The linear phase shift was reported recently in strongly-coupled atom-cavity systems49,50. The linear GFR in QD-cavity systems is responsible for both robust quantum gate oper- ations (in this subsection) and transistor operations (in the next subsection) although it has not been demon- st...
Single BJT Phase Shift Circuit You can have a lot of fun experimenting with audio phase-shift effects using this circuit. Q1 serves as a phase splitter, with the input signal connected to its base. The two outputs are interconnected through C2 and RV1, and you can access the output signal...
