An Energy-Efficient High-Swing PAM-4 Voltage-Mode Transmitter
As the data rate of high-speed I/Os continues to increase, four-level pulse amplitude modulation (PAM-4) is adopted to improve the bandwidth density and link margin at 50 Gb/s and
A high-speed PAM4 transmitter with T-coil peaking in 65 nm CMOS
In this paper, a PAM4 transmitter based CML is realized in 65 nm CMOS process. To get enough bandwidth for FFE data path and weighted combination module, multiple optimizing
PAM4 Signaling in High Speed Serial Technology: Test, Analysis, and
We''ll see that PAM4 signal analysis borrows a great deal from the jitter and noise analysis developed for PAM2-NRZ and that PAM4 technology at 25+ GBd will continue to benefit from the innovations that
A switched-capacitor based track-and-hold amplifier suitable for PAM4
In this paper, we propose the design of a track and hold (T&H) integrated circuit that is able to sample an incoming high-speed PAM4 signal and feed it to an analog to digital converter
