Application of switched-current technique to algorithmic DA- and AD-converters

As possible applications of the switched current technique, algorithmic DA- and AD-converters are presented. The design shows advantages in small power dissipation (3 mW) and in small area because of the use of very few MOS devices. Multichannel or more complex design does not increase the area too much if the possibility of sharing the same current sources is used. The circuit is implemented using a 2- mu m double-metal, N-well technology through MOSIS.<
