Abstract: This work aims to provide solutions and perspectives for CMOS analog designers by reducing the time spent in iteratively dimensioning the devices and simulating the circuits. For this purpose, by-hand design methodologies for a few analog cells are proposed employing a MOSFET compact model which has been earlier improved by adding sub-models for some second order effects. A semiempirical sub-model and characterization method is presented for the Early voltage, thus enhancing the set of model equations for hand calculations. The accomplishment of several by-hand design examples and the comparison between simulation results and specifications succeeded in demonstrating the usefulness and advantages of using the improved MOSFET compact model in the proposed methodologies.

Nanorennes (CNRS)

 
Nanorennes was created in 2007 as a regional micro-technological platform, labelled by french national center of research and science (CNRS). This platform gathers on the same institute the know-how and human beings dedicated to the fabrication of nano-micrometer sized devices, related to two research laboratories located in Rennes : IETR-GM (microelectronic group) and FOTON-OHM (photonic group).

Compact Unipolar XNOR/XOR Circuit Using Multimodal Thin-Film Transistors
in IEEE TED, vol. 68, no. 10, pp. 4951-4955, Oct. 2021,

Abstract: A novel compact realization of the XNOR/ XOR function is demonstrated with multimodal transistors (MMTs). The multimodal thin-film transistors (MMT’s) structure allows efficient use of layout area in an implementation optimized for unipolar thin-film transistor (TFT) technologies, which may serve as a multipurpose element for conventional and emerging large-area electronics. Microcrystalline silicon device fabrication is complemented by physical simulations.
