A Two Transistor Oscillator Circuit based on U.S. Patent 4,204,160  Figure One
Go To Home Page
This two transistor NPN oscillator uses two inductors and has  an oscillating frequency around 500 kHz.  The 33 pF capacitor was added for feedback coupling to make the circuit oscillate. One should refer to the actual patent at the U.S. PTO site for information on inductors L1 and L2.  This circuit is presented in Electronic Workbench 5.12 simulator format and it will start oscillating about 3 seconds after the simulation is started.  If the same circuit is simulated using Multisim 7, it will take about 30 seconds for the  oscillation waveform to occur.
