A Royer oscillator is an electronic relaxation oscillator that employs a saturable-core transformer in the main power path. It was invented and patented in April 1954 by Richard L. Bright & George H. Royer, who are listed as co-inventors on the patent. [1]
4 lut 2022 · 1) Transformer-feedback AF oscillator. In the figure below, you can see the circuit of an audio-frequency oscillator that utilises inductance-capacitance tuning and inducive feedback and holds a 2N2608 p-channel FET.
In the Armstrong oscillator design, the input is electromagnetically coupled with the output using a transformer to provide the 180 o of phase shift required for positive feedback.
16 mar 2021 · The 1st and 2nd circuit use the transformer both to rise the voltage and to make feedback in the oscillator. Both circuit use a pulse oscillator principle where the transistor at first conducts, but gets suddenly closed to unconductive (=no Ic) state.
Oscylator z strojonym kolektorem to transformator i kondensator połączone równolegle i przełączane tranzystorem. Ten układ jest najbardziej podstawowym schematem oscylatora LC. Pierwotna cewka transformatora i kondensator tworzą obwód rezonansowy, a wtórna cewka zapewnia pozytywne sprzężenie zwrotne, które zwraca część energii ...
