Re: QSD Models

Hi Phil,

The question I just ask about gain reduction as a function of phase clock skew is not the right question to ask. What we really are interested in is the gain from RF input to demodulated signal output. In the case of CW I would think this would just be the vector sum of the I and Q signals.

Another important question is if clock skew causes undesired signal response.

Hi all,

I've placed some results of simulation of a two switch and four switch
QSD circuit on my blog at:

Check it out if you are interested in the QSD circuits.
