Abstract :
We present in this paper a new Transimpedance Amplifier (TIA) for photoreceiver front-end circuit designed using 0.35 μm CMOS technology to be used in a functional near infrared spectroscopy (fNIRS) system. The main advantages of this circuit are low-power consumption (0.01 mW and 0.3 mW at 1 V and 3 V bias voltages) and high transimpedance gain (0.1 to 250 MV/A) accompanying with the tunable high bandwidth (1 kHz to 1 GHz), high-speed data rate and very low input and output noise, 1 fA/√Hz and 2 μV/√Hz respectively. The post-layout simulation results confirm the excellent performance of the proposed design compared to latest available photoreceivers.
