Abstract
A receiving method according to the present invention adjusts a level of an output voltage signal by switching a gain to be used for converting an inputted current signal to a voltage signal, in a preamplifier. Performing offset compensation on the output voltage signal in an offset compensator, in a post amplifier. Adding a reset signal, whose polarity is made opposite to a polarity of the output voltage signal, to the output voltage signal, in the preamplifier. Detecting the reset signal having added to the output voltage signal, and resetting the offset compensator by use of the detected reset signal, in the post amplifier.
