LOW VOLTAGE SUPPLY AMPLIFIER AND AMPLIFICATION METHOD

摘要

A high-gain, low power, electronic amplifier for amplification of a low magnitude voltage signal through a comparator-integrator amplification method for energy-aware applications is disclosed. The electronic amplifier comprises: a comparator arrangement with at least one comparator unit adapted to receive a first voltage signal to be amplified and a first feedback voltage signal, and to generate a first two-level voltage comparison signal; a integrator arrangement to receive the first two-level voltage comparison signal and generate a first amplifier output signal corresponding to an amplification of the voltage signal to be amplified; and a first feedback network to receive the first amplifier output signal and generate the first feedback voltage signal.
