Abstract

We developed a single mixed signal baseband chip performing all the necessary signal processing required for cellular phone communication in Global Systems for Mobile Communication (GSM) cellular terminals. The chip is a total GSM baseband solution consisting of voice codec, data converters, 100 MHz DSP, low power micro-controller, and ASIC. The device contains a 48k-word (16 bit) programmable instruction FLASH, an 8k-word Dual-Port Random Access Memory (DPRAM) for the data and instruction cache, and 4k-Bytes SRAM for the micro-controller. The chip size is 10.6×10.0 mm² including approximately 2.6M transistors and about 5000 analog components implemented in 0.35 μm 3 V linear FLASH CMOS technology
