Abstract-- PWAM transmitter combines pulse width modula-
tion (PWM) and pulse amplitude modulation (PAM) together to
boost the performance of the high speed serial link transceiver.
In this paper, two PWAM transmitter architectures are proposed
and the performances of them are compared based on the power
consumption analysis of the drivers. Bipolar driver is an energy
efficient choice for the PWAM scheme. It can save more than
half of the driver power consumption. The correct clock scheme
for phase selector is also discussed in this work.
I. INTRODUCTION
In recent years, the development of the data transmission
speed increases the demand of more sophisticated wireline
input/output (I/O) transceiver design. Therefore, some modu-
lation schemes and advanced technologies used in the field of
