This paper addresses the application of transimpedance amplifier (TIA) front-ends in biomedical imaging. Different topologies are studied and characterized, then the most appropriate structures are introduced. Three new TIA front-ends are proposed and implemented using standard submicron CMOS technology. The implemented TIA front-ends offer high gain-bandwidth product (GBW), low-power consumption (<1mW), high-transimpedance gain (up to 200MV/A), tunable bandwidth (0.1kHz-1GHz) and very low input and output noise (similar to few fA/root Hz and few similar to V/root Hz).
