A novel compact low-voltage, low-power two-stage non-conventional op-amp with rail to rail input-output swing and without Miller compensation is introduced. The input stage uses floating gate transistors and a dynamic biasing scheme. Experimental results of a test chip are presented that validate the proposed circuit operating with a single supply as low as 1.4 V.
