I am currently working on a LC Colpitts oscillator circuit and I am using LMV116 op amp for the oscillator.
The following is the schematics for the oscillator:
The inductance is 2.9uH, In order to oscillate at the frequency of 800KHz or a little higher, the capacitor should be nF range.
I placed the 1nF cap (C27 and C28), then the circuit started oscillating without the inductor attached to it. My guess is the LMV116 cannot drive
the cap with 1nF. So I am wondering what the maximum load capacitance LMV116 can drive.
If LMV116 cant drive nF range capacitors, are there any op amps will be more suitable for this application or can drive large cap?
