Hartley oscillator consists of a common emitter or common source amplifier which provides a phase shift of 180º.
In LC feedback network of 3 impedance which together provide an additional phase shift of 180º at the resonant frequency.
Thus total phase shift becomes 360° and oscillation occurs at f0.
X1 + X2 + X3 = 0
WoL1 + WoL2 - 1/WoC = 0
Wo( L1 + L2 ) = 1/WoC
Wo =
