Multi-Channel Multi-Gigabit Prbs Generator With A Built-In Clock In 0.18-Mu M Cmos Technology

In this paper, a parallel pseudo-random bit sequence (PRBS) generator circuit with a built-in clock was designed in 0.18-mu m CMOS Technology. For high-speed operation, the current-mode logic (CML) was used in the circuit. In the PRBS generator, four-channel 2-Gb/s and two-channel 4-Gb/s PRBS signals can be generated. The power consumption of the chip is 554.3-mW at 1.8-V of power supply, and the chip area is 1.196x1.01-mm(2). The PRBS generator can be suitable in multi-level modulation and multi-channel transmission tests.
