Abstract

We analyze the dynamics of a logarithmic transimpedance amplifier that are not explainable from its small-signal model. The amplifier was used both to measure pixel currents in an imager as well as currents from a floating gate array for accurate programming. We explain the marked asymmetry between the up-going and down-going current steps intuitively using circuit concepts and then based on phase-plane analysis. This analysis also helps develop a method of reducing the huge delay to down-going current steps. © 2007 IEEE.
