Hi all,
I think most of the guys here might have read before this paper: Simulating Switched-Capacitor Filters with SpectreRF.
On last line of Pg.11, there is a calculation using 4mkTRon where Ron is the on-resistance of the CMOS switch and is taken to be 2.3k ohms.
My question here is how did the 2.3k come abt?
I did plot the CMOS switch On-Resistance vs Vds curve.
The worst resistance is abt 4.9k ohm. 2.3k ohm is where Vds=0.
So which Ron value is it actually taken from?
Thank you in advance.
