Abstract :
The fact that many integrated circuits now operate from 3V power supplies, in particular, embedded controllers, memories, and a variety of logic chips, while only 5 V versions are available of some peripheral components has led to the use of mixed-voltage systems. The disadvantages of these systems are examined, and ways of dealing with them are discussed. Compared to systems using 5 V components only, the mixed systems offer the advantages of longer battery life and smaller size and weight.<>
