  • Abstract
    A single-chip analog transmitter (TX chip) for a V29-V32 9600-b/s modem has been implemented in a 3-μm CMOS n-well process. A high level of integration permits a low-cost, high-performance modem to be built. The TX chip is composed of analog, switched capacitor, and digital circuits. The important functions realized are the phase-point generator, the cosine roll-off low-pass filter, the modulator, and the programmable equalization filters. The chip occupies 29 mm2 and dissipates 300 mW
