| Abstract | Intelligent radio frequency (RF) front ends make use of MMIC and MEMS devices to provide a limited range of programmability to what have historically been fixed resistive, capacitive, and inductive impedance matching networks. Many BIST methods for mixed-signal systems can also be used to monitor and provide feedback for the control of such RF systems. For example, spectral techniques can be used to analyze and determine the center frequency of a bandpass filter. Information relative to the center frequency can then be fed back into the system, and adjustments can be made to fine tune the filter. In this paper, we outline our spectral based, mixed-signal approach for monitoring the health of analog and RF components in mixed-signal systems on-chip. In our approach we use well known DSP techniques based an the FFT for on-chip signal generation and analysis. We reduce required hardware by using the same functional block to analyze analog output signals that we use to generate m tone stimulus signals. By providing an on-chip functional test capability, we also reduce the test time required on expensive ATE. Our techniques have been prototyped and demonstrated on a Xilinx Virtex-II FPGA using an off-chip ADC and DAC, and we are currently implementing the technique on an ASIC using a 0.13 /spl mu/m process with target execution speeds of 2-16 GHz. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
