ABSTRACT:
A circuit, method and system for generating a non-linear transfer characteristic, including a plurality of current mirror circuits in parallel, each current mirror circuit having an offset current applied to an output terminal of an output-side transistor of the current mirror circuit for controlling an output current thereof, wherein the offset current of each current mirror circuit is set to a respective predetermined level, and the transfer characteristic is generated by summing the respective output currents of the current mirror circuits in a piece-wise manner.
