摘要：This paper deals with the design and analysis of folded cascode operational transconductance amplifier in different regions of operations: strong, weak and moderate inversion region. The folded cascode OTA consists of cascode OTA and cascode gain boosting technique. By using 0.35μm technology, the simulation shows DC gain of 78.42dB with a unity gain bandwidth of 446.07 MHz and power consumption of 412.77μW in strong inversion mode. The moderate inversion mode has a DC gain of 93dB and it provides unity gain bandwidth of 75.64MHz with a power consumption of 23.72μW. In weak inversion mode, it has 76.84dB DC gain with a unity gain bandwidth of 19.46 MHz and a power consumption of 0.1μW
