A 32/16-Gb/s Dual-Mode Pulsewidth Modulation Pre-Emphasis (PWM-PE) Transmitter With 30-dB Loss Compensation Using a High-Speed CML Design Methodology

Abstract

Pulse-width modulation pre-emphasis (PWM-PE) is a relatively new technique for compensating severe losses in wireline channels by varying the duty cycle of the transmitted pulse. The technique has been demonstrated upto 5 Gb/s and requires high-speed digital logic to accomodate narrow pulses in the transmitted bit stream. This work targets data rates beyond… (More)
