OBJECTIVES:
-> To explain the basic operational and design principles of CMOS Analog to Digital and Digital to Analog converter architectures.
-> To introduce the design calculations for developing the various blocks associated with a typical CMOS AD or DA converter.
-> To make students decide the dimensions and bias conditions of all the MOS transistors involved in the design.
