Abstract :
A 2.125 Gbaud Fibre Channel compliant preamplifler employs a common-gate input stage followed by a cascoded common-source stage with on-chip inductive gain peaking to achieve a 1.6 kΩ transimpedance and 0.6 μA input referred current noise, while operating with a photodiode capacitance of 0.6 pF. A fully differential topology ensures good substrate and supply noise immunity. The amplifier, implemented in a triple metal, single poly, 14 GHz f(Tmax), 0.5 μm CMOS process, dissipates 225 mW of which 110 mW is consumed by the 50 Ω output driver stage
