soi four-port network and its system

Abstract

The invention provides an SOI four-port network and a model topology structure thereof. The SOI four-port network comprises a first port, a second port, a third port and a fourth port; when an SOI device performs radio-frequency modeling, a grid is connected with the first port, a drain is connected with the second port, a source is connected with the third port, and a body electrode is connected with the fourth port. Due to the SOI four-port network, any structure of a common-source circuit, a common-grid circuit and a common-drain circuit can be adopted for modeling, and voltages of the ports are set as required. A body electrode of a traditional two-port network can only be grounded. The body electrode of the four-port network can be set so that radio frequency characteristics and noise characteristics under different body voltages can be obtained, and the modeling process can be more flexible.

Description

technical field [0001] The invention relates to the modeling field of radio frequency devices, in particular to an SOI four-port network and its system. Background technique [0002] With the development of integrated circuit technology and its more and more widely used, the requirements of high reliability, high performance and low cost must be considered in the design of integrated circuits. The function and accuracy requirements of cost analysis and reliability prediction are also getting higher and higher. In IC CAD software, the MOSFET device model is the key link between IC design and IC product function and performance. With the size of integrated devices getting smaller and smaller, the scale of integration is getting bigger and bigger, and the process of integrated circuits is getting more and more complex, and the requirements for the accuracy of device models are getting higher and higher. Today, an accurate MOSFET model has undoubtedly become the primary proble...
