| Abstract | A low flicker noise and high linearity passive mixer in 0.18µm CMOS is proposed. The mixer, which consists of gm-stage, AC coupled LO switch-pair and low noise trans-impedance amplifier (TIA), features a low flicker noise corner frequency of 5 kHz. The mixer is designed for direct conversion receivers in China Mobile Multimedia Broad-casting (CMMB) system. Simulation results show that the passive mixer achieves a voltage conversion gain (CG) of 21.2 dB, intercept point (IIP3) of +13 dBm, double sideband (DSB) noise figure (NF) of 18.9 dB @ 5 kHz, white DSB NF of 18.1 dB, and output DC offset of less than 3mV. The mixer dissipates 7.2 mA (including I path and Q path) from a 1.8 V supply. |

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.
