M. Helfenstein et Gs. Moschytz, CLOCKFEEDTHROUGH COMPENSATION TECHNIQUE FOR SWITCHED-CURRENT CIRCUITS, IEEE transactions on circuits and systems. 2, Analog and digital signal processing, 42(3), 1995, pp. 229-231
A new clockfeedthrough compensation scheme for switched-current system
s is proposed. The circuit cancels both the signal dependent and the c
onstant clockfeedthrough term. It is shown that this concept can be us
ed to derive various sample-and-hold circuits, depending on the desire
d clock frequency, accuracy, and power dissipation.
