Submission for CAS Transactions Papers: Design Methodology Based on the Inversion Coefficient and its Application to Inductorless LNA Implementations

The Internet of Things (IoT) entails new challengesfor the development of wireless transceivers. Radio-Frequency building blocks require complex design flows in order to address very different sets of specifications. This paper presents a three-step design methodology dedicated to the synthesis of RF building blocks. Based on the Inversion Coefficient, the proposed design methodology allows the optimization of the circuit performance for any CMOS process and any application. It is illustrated through the implementation of inductorless Low-Noise Amplifiers (LNA) in three different CMOS nodes: 28 nm Fully-Depleted Silicon-On-Insulator (FDSOI), 65 nm and 130 nm Bulk. These LNAs are dedicated to two cases of IoT applications: multi-standard and ultra low power. The proposed circuits achieve state of the art performance for all nodes and applications. Furthermore, the methodology enables an insightful comparison of the capabilities of the different CMOS nodes in terms of power consumption, noise and bandwidth.
