Researches in the Computer Aided Innovation System based on Extenics are very few, and we have developed the Web service-based Extenics aided innovation system according to the Extenics innovation process, meanwhile, we introduce the specific detail of the hierarchical structure as well as the design and deployment of Web services supporting this system. At last, we give a case to show how to guide innovative personnel to deduce their innovative thoughts on the contradiction of the problem.

In this paper, we present a novel enhanced recycling folded cascode (ERFC) operational transconductance amplifier (OTA), which exhibits high efficiency and a fast transient response under weak inversion. Our innovative combination of adaptive biasing with nested local feedback (ABNLF) effectively enhances the input transconductance and slew rate (SR), thus improving the transient response. By incorporating coupling capacitors at the output stage, we achieve a stable operating region with large signal responses. Both the traditional RFC OTA and the proposed ERFC OTA were designed in a 0.18 $\mathsf{\mu }$m CMOS process, operating at a power supply of 1.8 V, with quiescent currents of 8 $\mathsf{\mu }$A and 10.4 $\mathsf{\mu }$A, respectively. Post-layout simulations reveal a remarkable enhancement in the proposed ERFC OTA over the traditional RFC OTA, with the SR and gain–bandwidth (GBW) surging by 120- and 5.95-fold, respectively. This advancement boosts the efficiency of the traditional RFC OTA and provides an impressive figure of merit (FoM) of 130.04 (V/$\mathsf{\mu }$s)·pF/$\mathsf{\mu }$A.
