A 5gb/S 3.2mw/Gb/S 28 Db Loss-Compensating Pulse-Width Modulated Voltage-Mode Transmitter

A voltage mode transmitter employs pulse width modulation (PWM) based equalization of NRZ input data at 5Gb/s and compensates 28 dB channel loss at 2.5GHz. Fabricated in a 90 nm CMOS process, the proposed transmitter achieves a horizontal eye opening of 0.3 UI with BER < 10(-12) and consumes only 16 mW power of which 2.5 mW is consumed by the digital PLL.
