| Abstract | It is very important to analyze the mixer and modulator circuits which are driven by multiple input frequencies. Volterra series methods are widely used for the frequency-domain analysis of nonlinear circuits, which can be applied to relatively strong nonlinear circuits. We compare properties of the above two methods using illustrative examples. In this paper, we propose a Spice-oriented HB method combining with MATLAB. Firstly, for the circuits containing nonlinear devices characterized by the special function, they are approximated by the Taylor series. Then, the Fourier coefficients can be calculated by MATLAB in the symbolic forms. Thus, the determining equations of HB method can be formulated by net-list in Spice simulator. It can be efficiently solved by the DC analysis of Spice, and the frequency-domain solutions are obtained. We found from examples that, although Volterra series method can be efficiently applied to weakly nonlinear circuits, it becomes erroneous to strong nonlinear circuits. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
