Abstract :
A low-voltage tunable transimpedance amplifier destined for optical-fibre communication front-ends in the standard Gigabit Ethernet is presented. Designed in low-cost 0.35 mum CMOS technology, the circuit works with a single 1.8 V supply voltage, consumes only 6.2 mW, and exhibits a transimpedance tunable range of 50-65 dB Omega with bit rates higher than 1.25 Gbit/s.
