CMOS wideband amplifiers using multiple inductive-series peaking technique

This work presents the technique of multiple inductive-series peaking to mitigate the deteriorated parasitic capacitance in CMOS technology. Employing multiple inductive-series peaking technique, a 10-Gb/s optical transimpedance amplifier (TIA) has been implemented in a 0.18-μm CMOS process. The 10-Gb/s optical CMOS TIA, which accommodates a PD capacitor of 250 fF, achieves the gain of 61 dBΩ and 3-dB frequency of 7.2 GHz. The noise measurement shows the average noise current of 8.2 pA/√Hz with power consumption of 70 mW.
