N2 - This paper proposes a comprehensive model of capacitive feedback transimpedance amplifiers, based on an analysis of the parasitics and non-idealities of the system. The proposed model is in good agreement with circuit simulations (less than 2% error on the gain and 18% on the bandwidth for large set of parameters), and allows to compute the analytical boundaries of the capacitive topology. Finally, a comparative assessment between capacitive and resistive topologies in terms of performance is proposed and highlights the salient performances of capacitive feedback transimpedance amplifiers.
