Abstract
A single chip analog transmitter (TX-chip) for a V29- V32 9600 bit/sec modem has been implemented in a 3μ CMOS process. A high level of integration permits a low cost, high performance modem to be built. The TX-chip is composed of as well analog, SC, and digital circuits. The important functions realised are the phasepoint generator, the cosine roll off lowpass filters, the modulator and the programmable equalization filters. The chip occupies 29 mm* and dissipates 300 mW.
