The GBTIA, a 5 Gbit/s radiation-hard optical receiver for the SLHC upgrades

Abstract : This paper presents a 4.8 Gbit/s optical receiver designed in a 0.13 μm CMOS process as part of the GBT project. The receiver consists of a transimpedance amplifier (TIA) and a limiting amplifier. A differential cascode structure with inductive peaking is adopted for the TIA to achieve high gain, high bandwidth and low input referred noise. Experimental results at room temperature show an open eye diagram at 4.8 Gbit/s with rise time < 40 ps, a bandwidth of 4 GHz, and a sensitivity of < -16 dBm for a BER of 10-12. The total chip power consumption is < 120 mW.
