Popis: A description is given of a mixed analog/digital chip that forms the core of a low-speed modem for use over standard telephone lines. It meets CCITT and AT&T requirements for data transmission at 1200 and 2400 b/s and the AT&T requirements for 300-b/s operation. The chip is implemented in a 1.75- mu m analog CMOS process and occupies 32.4 mm/sup 2/. The device is powered by a single +or-5-V supply and consumes less than 115 mW. The architecture and circuit implementation are described, and experimental results are given. >
