A 21mW 2.5Gb/s 15kΩ self-compensated differential transimpedance amplifier

A differential transimpedance amplifier combined with a positive feedback compensation circuit tolerates 1.5 pF parasitic capacitance from ESD protection in 0.35 /spl mu/m SiGe BiCMOS. A 2.5 Gb/s optical receiver demonstrates 15 k/spl Omega/ transimpedance gain and DR from -3 to -23.5 dBm while consuming 21 mW from a 3 V supply.
