Abstract

An input amplifier network (1.1) has amplifiers which amplify an input analog signal and generate multiple analog signals. The amplifiers are weighted in a way one amplifier generates a largest linearly amplified analog signal. Selectors (1.2,1.3,1.6,1.7) choose the largest linearly amplified analog signal. A/D converting units (1.4,1.5) convert the largest linearly amplified analog signal to digital output signal.
