Hi all,
I'm trying to a LNA (untuned common emitter amplifier) for my FM receiver to amplify the RF signal from the antenna before sending it into the oscillator.
Although the signal is being amplified, but it's no longer a perfect sine wave (when i input a sine voltage). Here's the simulation i obtained from ADS. I was hoping someone could advice me on this matter.
Thanks in advance.
