lc oscillator buffer
Hello,
I have designed a crosscoupled LC oscillator as shown in the following picture which operates at 1.8GHz, in 3V supply voltage and has a sinusoidal peak to peak voltage swing of 2V. My question concerns the output buffer that follows the oscillator core.
What kind of buffer should I use in order to have a 50 Ohm termination?
Will the large swing voltage affect the shape of the outputs after the buffer?
Thanks for any help!
