A 10-Gb/s trans-impedance amplifier (TIA) with insensitive characteristics to photodiode junction capacitance is demonstrated in 0.13-µm CMOS technology. The TIA has LC-ladder input configuration which allows large bandwidth even with large photodiode capacitance (CPD). In addition, the circuit bandwidth is enhanced with capacitive degeneration and shunt peaking techniques. With CPD of 1.5-pF, our TIA has about two times larger bandwidth compared with conventional TIAs.
