Hi!
I made an opamp hartley oscillator using a certain electronics simulator and even though simulation takes place I'm unable to get any oscillation at all. I tried first using Rf and R1 equal to 1kΩ and two inductors both of whch are 50 mH. The capacitor value is 0.01 µF. I've used a generic op-amp. I've attached a snapshot of the circuit. This simulator uses qucs models of components. I checked the tank circuit separately and gave it an instantaneous voltage and it gave oscillations. But its not helping in this circuit. what could be the problem? I even tried giving a dc offset to the output to imitate the dc offset of a real opamp.
