Fundamental Frequency for transient simulation tool is set to 1GHz.
Since this is Common Drain, VOUT should at most have the same amplitude as VIN. Probably even negative shift, since I didn't change the voltage threshold (I haven't got to tweaking parameters yet). So what's up with the positive DC bias?? Why is the amplification significantly less than unity?
1.) Also, what's that Transient Response at the very first cycle of VOUT? Why would a semiconductor have a Transient Response? Is it because of the "inductance" on the drain and source of a MOSFET?
2.) Lastly, why is it that this simulation does not work on very low frequencies? I first started with 1Hz scale for everything (just change all units from 1GHz below to 1Hz). The M1 just acted like a 1kOhm constant resistor.
Because of recent response, I bothered to simulate this in the 1kHz scale (replaced all units from GHz in the pics to kHz, did the same with Fundamental Frequency) -- really should've done that in the first place (stupid me). This is the output:
Even here, the DC bias is nearly the same and the amplification is much, much less. It also lags by 90°. Why?
I'm starting to think it's either just using the wrong component or there was a set of parameters to fill-in for this component to get this to work.
