Hartley Oscillator:

Figure 1, shows Hartley oscillator when LC tank is resonant, the circulating current flows through L₁ in series with L₂. Thus, equivalent inductance is L = L₁ + L₂.

Figure 1

In the oscillator, the feedback voltage can be developed by the inductive voltage divider, L₁  & L₂. Since output voltage appears across L₁ and feedback voltage across L₂, the feedback fraction can be given by

β = V / V_out = XL₂ / XL₁ = L₂ / L₁

As usual, loading effect of the base is ignored. For the oscillations to begin, the voltage gain should be greater than 1/ β. The frequency of oscillation can be given by

Likewise, an op-amp based Hartley oscillator circuit is shown in the figure 2.
