This paper presents a high unity gain bandwidth fully differential folded-cascode operational amplifier using gain-boosted technique. The amplifier is designed in TSMC 0.18μm 1P6M CMOS technology. The unity-gain bandwidth (GBW) and poles of the gain-boosting amplifiers were carefully designed to improve the stability. The implemented design provides a direct current (DC) gain of around 93 dB with a unity gain frequency of 1.8GHz. It exhibits a DC gain larger than 88dB when the output common-mode voltage between 0.6 V and 1.2V. the overall layout size is 96μm×120μm.
