An analysis method of an electrometric amplifier using two pumped low-reverse-current silicon diodes is described. First, a mathematical model representing the i(v) characteristic near the zero, where the surface effects are the most important, is proposed. Then, from this general model, both input resistance and amplifier-sensitivity coefficients are calculated.
