CMOS Inverter LC Oscillators

[Aziz]

I have searched the day long for some LC oscillators. I found two interesting LC oscillators for testing.

or

These LC oscillators are very easy to build and they deliver more power. I will test some of them for the laptop MD. By changing the cmos inverter type, more voltage can be applied (up to 15..20 V).

Has anyone some similar LC osc. schematics?

G`day Aziz

Dont know if this is what your after,i found this on the web some time back,see what you think,i also have the same cct but with varacters.
If you have interest i can give you web site.

Hi ZED,

thanks for your effort. I had already found this site:

But I found a patent, to make such oscillators stable. Look at this:

This seams quite interesting. I will make some modifications on the CMOS LC osc. to see whether there is more potential available. When got a stable LC osc., the lock-in amplifier will work perfectly to achieve more SNR.
