A 0.18 μm CMOS multi-Gb/s 10-PAM transmitter

초록

A multi-Gb/s transmitter using multi-level pulse amplitude modulation (M-PAM) is presented. 10-PAM enables transmitter to decrease the symbol rate compared to binary signaling. The transmitter transmits data in current-mode instead of voltage mode, so that high switching speed of driver is achieved. Besides core blocks of the transmitter, Pseudo random bit sequence (PRBS) generator was designed for built-in self-test (BIST). The 10-PAM transmitter is designed in 0.18 mu m CMOS process and achieves 3.2 Gb/s with 1.8 V supply voltage.
