Abstract

A new sampling technique is proposed, which integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. Both the theoretical deduction and the simulation prove the advantages of improving the speed and accuracy of CMOS sampling circuits. A practical charge sampling circuit with 3 V supply, 500 MS/s and 9-bit accuracy is suggested.
