We designed two optical-link ASICs for a new pixel layer of ATLAS. The ASICs include a 5 Gb/s driver for a 12-channel VCSEL array and a receiver/decoder to extract the data and clock from a 12-channel PIN array. The performance of the ASICs is satisfactory, including the ability to bypass broken PIN/VCSELs and set the ASICs to a default configuration with a power-on reset circuits in an event...

A chip is developed in a 130nm technology, containing a transimpedance amplifier with a 405MHz bandwidth, 89dBΩ transimpedance gain and a dynamic input range of 1:1600 for a photodiode capacitance of 0.75pF. The equivalent input noise is 216nA. The gain of the voltage amplifier, used in the TIA, degrades less than 3% over a temperature range from −40°C up to 125°C. The transimpedance-bandwidth...

The GigaBit Laser Driver (GBLD) is a radiation tolerant ASIC which is part of the GigaBit Transceiver (GBT) chip-set. It is aimed to drive both edge emitting and VCSEL laser diodes at a data rate in excess of 5 Gb/s. The GBLD can provide a modulation current up to 24 mA and a bias current up to 43 mA.Pre- and de-emphasis functions are implemented to compensate for high external capacitive...
