Abstract :
A new clockfeedthrough compensation scheme for switched-current systems is proposed. The circuit cancels both the signal dependent and the constant clockfeedthrough term. It is shown that this concept can be used to derive various sample-and-hold circuits, depending on the desired clock frequency, accuracy, and power dissipation
