Abstract :
As technology advances offer small size and light weight in mobile telecommunication equipment, low power techniques become important elements. This paper describes the design techniques for very low power consumption, solving hardware implementation issues. Basically they were applied to the speech codec in a personal digital cellular phone and their effectiveness was verified
