LVLP high Gm bulk-driven folded cascode OTA using current shunt auxiliary pair

In this paper, two techniques are proposed using bulk-driven approach, which improves the performance of OTA. The proposed OTAs are designed and simulated on Tanner EDA Tool using 0.18 μm standard CMOS process technology. The effectiveness of using the current-shunt auxiliary amplifier, folded-casco...

Summary:In this paper, two techniques are proposed using bulk-driven approach, which improves the performance of OTA. The proposed OTAs are designed and simulated on Tanner EDA Tool using 0.18 μm standard CMOS process technology. The effectiveness of using the current-shunt auxiliary amplifier, folded-cascode amplifier and replica chain self-biased technique in bulk-driven OTA results in improved DC gain and GBW at the cost of power consumption.
