4 benjamin lutgen given objectives objective of the project: In this paper, we present a systematic and automated design flow for the most popular integrated circuit ota architecture, namely, the folded cascode ota. Tradeoffs among such factors as bandwidth, gain, phase margin, bias currents, signal swing, slew rate, and power are made evident. These measures are fixed by various parameters.
