In this paper, a transimpedance amplifier (TIA) based on floating active inductors (FAI)\nis presented. Compared with conventional TIAs, the proposed TIA has the advantages of a wider\nbandwidth, lower power dissipation, and smaller chip area. The schematics and characteristics of the FAI\ncircuit are explained. Moreover, the proposed TIA employs the combination of capacitive degeneration,\nthe broadband matching network, and the regulated cascode input stage to enhance the bandwidth and\ngain. This turns the TIA design into a fifth-order low pass filter with Butterworth response. The TIA is\nimplemented using 0.18 microm Rohm CMOS technology and consumes only 10.7 mW with a supply voltage\nof 1.8 V. ......................................
