Abstract :
It is shown that a multichannel sample-and-hold amplifier with weighted integration can perform internal antialiasing filtering when its weight function and the number of channels are properly selected. The advantages of internal antialiasing filtering, which allows the removal of a conventional antialiasing filter, are especially significant in digital receivers
