Abstract :
In this paper, the analytical expressions of the buried double junction (BDJ) leakage currents are proposed. Associated to the photocurrents equations, the BDJ equivalent electrical circuit is deduced. However, in order to not limit this model to the photoconductive mode, an extension of the Ebers-Moll equivalent circuit is adopted. Next, the incremental AC model, as well as the noise model of the device have been obtained. Measurement shows good agreement with simulation, hence validating our model
