Automated Generation Procedure for Fully Differential Op-Amp Using TED

This paper proposes an automated generation method which encompasses the entire process from performance specifications to layout for the fully differential gain-boosted operational amplifier (op-amp). At the schematic level, this process uses the g

methodology to automatically explore solution spaces and determine dimension(W/ L) of transistors to meet performance constraints. By transition of pre-computed lookup table across technologies, it achieves design migration. At the layout level, leveraging Tsinghua Electronic Design (TED) enables direct conversion of parameter of circuit into layouts. Experimental results show this process can generate sized circuits and layouts meeting requirements across various technology and performance specification.
