The pixel density of the front-end detectors continues to rise, and with it the power they consume—now stretching into the watt range—while the cable mass and thermal budget of the detector volume remain essentially fixed. Today's arrays are powered in parallel at low voltage and high current (roughly 2 V/24 A), a scheme that already strains the cable budget and the associated I²R losses. This...
High-energy physics experiments require increasingly high-speed data transmission in front-end readout systems. Based on our prior designs and measurements, the 10-Gbps NRZ transmission is approaching the bandwidth limit of the 55-nm CMOS process. Consequently, PAM4 transmission technology, which doubles the data rate within the same analog bandwidth, presents an attractive alternative.
The...
