Title: sample switch
Post by cktlife on Aug 22^nd, 2007, 8:17am

Hi all,

T/H switch has the issue of charge injection and clock feedthrough. I wonder if there is any way or paper to estimate the settling time of charge injection onto the hold capacitor.

Thanks,

The charge injection and clock feedthrough may introduce distortion and offset. However, I don't think it will impact the settling time.
