Abstract :
The development of an adaptive vector quantizer (AVQ) CODEC chip using open architecture silicon implementation system (OASIS) tools is presented. The goal of this effort is development of a 16-kbps AVQ coder prototype system which can be used as an alternative to the currently used 32-kbps adaptive delta pulse code modulation (ADPCM). The AVQ semi-custom chip layout uses 1.2-μm SCMOS technology and consists of over 157000 transistors. The AVQ system is being designed with Mentor Graphics tools and is a 4-layer PC board encompassing over 50 analog and digital components
