Abstract

PURPOSE:To enable to perform excellent amplifier selection, by giving parallel differential amplifiers taking a plurality of inputs independently for at least one stage in multiple and direct connection, and by interrupting each constant current source of the amplifiers in DC and by amplifying only the desired inputs.
