Abstract

In this paper, a low Power, Gain Boosted Recycling Folded Cascode Operational Transconductance Amplifier (GB-RFC OTA) is described. The proposed GB-RFC OTA is designed using 130nm CMOS technology and achieves enhanced gain, unity gain bandwidth and slew rate with the low Power budget. The proposed circuit operates on 1V supply voltage and 200 µA bias current and consumes a power of 798µW. The GB-RFC has about 24dB higher gain and 37MHz higher unity Gain Bandwidth (GBW) compare to Double Recycling Folded cascode OTA (DRFC).
