ANALOG DISCRETE TIME FILTER, RECEIVER SYSTEM INCLUDING THE SAME AND DISCRETE TIME FILTERING METHOD

摘要

An analog discrete time filter comprises a transconductance amplifier which converts one input voltage signal into multiple current signals; a switch matrix which controls weighted values of the current signals in response to multiple switching control clocks; a sampling capacitor bank which samples charges corresponding to the current signals with the controlled weighed value and outputs the sampled charges in response to multiple output control clocks; and a clock generator which generates the switching control clocks and the output control clocks.
