| Abstract | A 0.8-V CMOS coupling current-mode injection-locked frequency divider (CCMILFD) with 19.5% locking range and a current-injection current-mode logic (CICML) frequency divider have been designed and fabricated using 0.13-mum 1p8m CMOS technology. In the proposed CCMILFD, the current-mode technique to minimize the loss of input signals and the coupling circuit to enlarge the phase response have been designed to increase the locking range. The locking range of the fabricated CCMILFD is 4.1 GHz with a power consumption of 1.51 mW from a power supply of 0.8 V. In the proposed CICML frequency divider, the current-injection interface is applied to the current inputs to make the circuit operated at a higher frequency with low power consumption under a low voltage supply. The operation frequency of the fabricated CICML frequency divider can divide the frequency range from CCMILFD and consume 1.89 mW from a 0.8-V voltage supply. The chip core areas of the CCMILFD and CICML frequency divider without pads are 0.23 and 0.015 mm2, respectively. The proposed circuits can be operated in a low supply voltage with the advantages of a wider locking range, a higher operation frequency, and lower power consumption. |

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.
