Improved recycle folded cascode OTA with current control circuit / Nordiana Mukahar and Siti Aishah Che Kar

This paper presents an improved architecture of folded cascade OTA with current control circuit that achieves improved DC gain and settling time without sacrificing power and area. This is achieved by exploiting and using idle device in the signal path and separates the AC and DC path, which res...
