Abstract :
Conventional CDMA serial links suffer from the drawback that the number of transmitters is limited to only two in practical implementations due to the reduced voltage spacing between adjacent logic states of the transmitted data. In this paper, we propose a new CDMA serial link architect that allows an arbitrary number of transmitters to transmit data over the same channel simultaneously while keeping the voltage spacing between adjacent logic states of the transmitted data to be the same as that of 4-PAM serial links. The effectiveness of the proposed architect is validated using the simulation results of a serial link with four transmitters designed in an IBM 130 nm 1.2V CMOS technology.
