A PAM-8 Wireline Transceiver With Linearity Improvement Technique and a Time-Dom

Abstract

This article presents a pulse-amplitude-modulated (PAM)-8 wireline transceiver with receiver-side pulsewidth- modulated (PWM) or time-domain-based feedforward equalization (FFE) technique. The receiver converts the voltage-modulated signals or PAM signals into PWM signals and processes them using inverter-based delay elements having a rail-to-rail voltage swing. Time-to-voltage and voltage-to-time converters are designed to have non-linearity with opposite signs with the aim of achieving higher
