Comments on Op Amp Hartley oscillator

Post

Op Amp Hartley oscillator

+0
−2

Im designing a Hartley oscillator this time with a opamp providing the open-loop gain.I have tried drawing the small-signal analysis of my circuit to use KVL and KCL to find the conditions of operation of my Hartley oscillator but now I am stuck.

How should I continue ?

Incorrect schematic for a Hartley Oscillator

The op-amp (beyond its local feedback) needs to have a resistor in series with the output that feeds the first inductor L1 else, it's not a Hartley oscillator. Please learn how to draw schematics correctly.
