Abstract
A single-stage fully differential operational amplifier has a high open-loop gain and can be incorporated in a very small area of silicon and has a very small number of bias interconnection lines. The amplifier includes two identical arms each having similar bias and loads, transconductance and common-mode feedback elements. Each of the aforementioned three elements in each branch have the same current flowing therethrough when the amplifier is quiescent.
