Abstract :
A programmable operational amplifier (OpAmp) concerning noise and power consumption is described. Key design issues for achieving programmability of a preselected OpAmp architecture are discussed. Experimental results for a 0.35 mum CMOS OpAmp show either ultra low noise of 2 nV/radicHz or low power consumption of 140 muW. The OpAmp remains stable over the whole range of programmability
