A fully digital operational transconductance amplifier (DIGOTA) architecture for tightly energy-constrained low-cost systems is presented. A 180-nm DIGOTA testchip exhibits an area below the 1000-mu m(2) wall, and 2.4-nW power under 150-pF load, and a minimum supply voltage V-min of 0.25 V. In the 0.3-0.5-V supply range, DIGOTA improves the area-normalized small (large) signal energy FoM by at least 836x (267x) over prior sub-500-mV OTAs, while reducing area by 27x-85x. The low-V-min and nW-power features are shown to enable direct harvesting at the mm-scale.
