Low voltage, low power 13-bit linear voice codec with programmable analogue frontend

A low-voltage, low-power 13-bit linear voice codec has been developed and implemented in 1.2 /spl mu/m CMOS technology. At single supply voltage greater than 2.6 V and power dissipation of 20 mW it fulfils or exceeds all NET33 recommendations for digital handset terminals. Active area for a complete codec is 29 mm/sup 2/. It can be used as an analogue frontend for DSP, digital cordless telephone, a digital cellular telephone or a digital answering machine.<
