A novel CMOS current feedback op-amp is presented. The solution works using a low supply voltage and provides a wide input/output swing as well as a high current driving capability. Experimental results from a prototype implemented in a 0.35-mu m technology and powered with 1.5 V are also given. The circuit exhibits a better than 500 kHz closed-loop bandwidth and a +/- 1 mA current drive capability.

Abstract
A novel CMOS current feedback op-amp is presented. The solution works using a low supply voltage and provides a wide input/output swing as well as a high current driving capability. Experimental results from a prototype implemented in a 0.35-mu m technology and powered with 1.5 V are also given. The circuit exhibits a better than 500 kHz closed-loop bandwidth and a +/- 1 mA current drive capability.File in questo prodotto:
