| Abstract | We report a high performance NPN bipolar junction transistor (BJT) processed in standard CMOS process that is applied to realize the direct conversion GSM receiver and DVB-H tuner. Through the variation of the base doping profile, performance of the NPN BJT has been tailored to meet the requirements of the RF circuits. Careful optimization is performed using both simulation and experiment. Optimized NPN BJT has maximum current gain of ~44, collector-emitter breakdown voltage of ~7V, collector-base breakdown voltage of ~20V, early voltage of ~25V, cutoff frequency of ~8.0GHz, and maximum oscillation frequency of ~11.6GHz. Low frequency noise characteristics of the NPN BJTs are investigated and the best structure for low noise level is identified. The corner frequency of the 1/f noise is ~2kHz at a collector current of ~1.7mA, which is ~4 orders lower than that of NMOS. As the flicker noise level is much lower than the CMOS, NPN BJT is used to realize the zero intermediate frequency (ZIF) direct conversion receiver (DCR) for GSM transceiver and DVB-H tuner. The resulting GSM receiver chain has a gain of over 50dB and noise figure of 2.5-3.0dB. For DVB-H tuner operating in the range of 470-850MHz, NF of 4.5dB and IIP3 of -5dBm are achieved at a gain of 64dB |

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.
