Abstract

See full text

A return-to-zero current-steering DAC is presented. The presented return-to-zero technique can isolate the analog output nodes of the DAC from the coupling of the control signals of the DAC without sacrificing speed. The topology uses a bank of return-to-zero circuits, which employs return-to-zero and isolation transistors to implement the presented return-to-zero technique.
