| Abstract | As one way of reducing the reliance on mixed signal testers for circuits with small analog content, researchers have proposed built-in self-test (BiST) techniques that target specific parameters of analog circuits. Most BiST techniques for phase locked loops (PLL) aim at measuring the timing jitter through precise on-chip clocks and/or additional computation of measured specs. In this paper, we propose a built-in test circuit to perform go/no-go testing for in-band PLL phase noise. Our circuit measures the band-limited, low frequency noise power at the input of the voltage controlled oscillator (VCO) which is translated as the high frequency phase noise at the output of the PLL. Our circuit contains a self calibration sequence based on a simple sinusoidal input to make it robust to process variations. The circuit is implemented using 0.8mum CMOS process with the equivalent area of roughly 800 2-input minimum size NAND gates. Monte Carlo simulations have confirmed that the test circuit can robustly detect noise levels that are above the specified fail level |

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.
