The transformer feedback oscillator is also called mutual-inductance coupling oscillator and it's typical circuit is showed as picture 5-6.The resonant amplifier is composed of transistor,bias circuit and frequency network.Cb is blocking couplingcapacitor,Ce is emittingbypass capacitor .It is coupled via L1L and the L1 feedback voltage is added to amplifier's input end.The sine wave output voltage obtained from load RL by L1L mutual-inductance coupling.
