ABSTRACT:
An amplifier has a pair of common source transistors in which the sources are coupled together during a first mode of operation and isolated from each other during a second mode of operation. A current source provides current between a power supply terminal and these sources during the first mode and prevents current flow therebetween during the second mode. A pair of switchable loads act as loads for the common source transistors during the first mode and are switched off during the second mode.
