Abstract
This paper designed a low-noise high-gain tran simpedance amplifier with high dynamic range. The input stage of TIA uses an individual power supply to accommodate the level of the photodiode(PD). Then the signal is transmitted to the subsequent circuit by a level shifting circuit. The TIA adopts DCrestore to stabilize work points, and uses a MOS working in the linear region to reduce the effective input signal to realize high dynamic range. Key noise components are optimized to reduce the input referred current noise. This TIA was validated in 0.13 urn CMOS. The simulation results show the -3dB bandwidth is 1.8GHz, the maximum gain is 82.27dB Ω, the input referred noise is 125nA, and the measure current ranges 5uA ~2mA.
