Abstract:Abstract:The DC open-loop voltage Gain is a very important specification for amplifiers. In order to increase this specification, in this paper, we have proposed an improved folded cascode gain boosted amplifier (improved FCGBA) which has extremely large DC open-loop voltage gain. Compared to traditional FCGBA, this novel structure needs only one auxiliary amplifier, so it is energy saving. Finally, with SMIC 0.18 μm CMOS process of 1.8 V supply and Hspice simulator, a corresponding amplifier with a capacitor … Show more
