“…The block diagram of the driver is presented in the figure 1. The architecture is based on the source-series-terminated (SST) transmitter [8][9][10]. The output stage is segmented to enable adjustment of the output current which is desirable in order to compensate for process voltage temperature (PVT) variations and adapt to various loads.…”

The paper presents the Dual Use Driver (DUDE) for high speed links, a circuit designed for the Demonstrator ASIC for Radiation-Tolerant Transmitter in 28 nm CMOS (DART28) developed under the EP-R&D programme on technologies for future high energy physics experiments. The driver operates at 25.6 Gbps and it allows driving both 100 Ω transmission lines and optical Ring Modulators (RMs) integrated in a photonics integrated circuit (PIC). The driver includes configurable pre-emphasis. The device will allow to demonstrate the feasibility of wavelength division multiplexing (WDM) optical links operating with bandwidths in excess of 100 Gbps per fiber that are capable of sustaining total ionizing radiation doses up to 10 MGy.

This study presents an 8 Gbps low-power source-series terminated (SST) transmitter for high-speed serial links. The proposed transmitter consists of a novel hybrid 20:2 multiplexer followed by a three-tap feed-forward equalizer (FFE) and a shunt path SST driver. In addition, a high-precision impedance calibration circuit with slice unit replication is proposed to match the characteristic impedance of channel, whose maximum calibration error is 0.002%. Fabricated in 55-nm CMOS technology and has area of 0.024 mm 2 . Measurement results show that the transmitter achieves data rate of 8 Gbps while maintaining good performance. The transmitter has output swing of 510 mV with −6 dB post-tap equalization, and it consumes 15.1 mW under 1.2 V power supply.
