hi all,
I have one question about the sampled pnoise simulation:
If I have a switched capacitor sample and hold circuit to sample the noise of resistor R, and now I add another switch sampler just paralleled with the first switch, with same sampling freq (fs) but nonoverlapping. so, the pss fund. freq = fs, but essentially the switch freq is 2fs.
how can simulate the circuit to get the right noise density (4kTR*pi/2*f3db/fs), instead of 4kTR*pi/2*f3db*2/fs?
thanks
Jeff
