DESIGN OF 8-BIT CURRENT STEERING DIGITAL TO ANALOG CONVERTER USING FULL SWING GDI LOGIC

A low - voltage low - power small - area digital to analog converter (DAC) for high speed applications is introduced in this paper. A current steering digital to analog converter is well suitable for high speed application, because all the currents taken from the supply is used for the outpu t signal. In this paper it deals with the design and analysis of an 8 - b it current steer ing digital to analog converter which was implemented using full Swing (FS) GDI Logic in CMOS process. The active area of this pr oposed DAC was reduced to four times in a standard 1P3M 0.13 μm 3.3 V CMOS process, b oth the INL and DNL were reduced to half of 8 - bit DAC implemented using conventional logic gates .
