Abstract :
A consideration for an analog antialiasing filter performance, addressed to a nonuniform sampling coding technique was described. The filer prototype design and its implementations are presented. The Sallen-Key architecture based on CMOS inverters and the solution of achieving resistor formed by transmission gates with long MOSFETs are presented. Finally the simulation results are discussed.
