| Abstract | A broadband complementary metal-oxide semiconductor (CMOS) single-pole-double-throw (SPDT) switch based on a travelling-wave design with using dual-gate N-type metal-oxide semiconductor (NMOS) transistors is implemented in a 0.18 μm CMOS process for millimetre-wave applications. To further investigate the power handling capability in a dual-gate metal-oxide semiconductor field-effect transistor (MOSFET), this study analyses the mechanism of voltage swing distribution by using the proposed large-signal cascode model. Considering the parasitic gate-to-gate capacitance and the substrate effect, the simulations in this study can accurately predict the small-signal and power handling performances of the SPDT switch. The switch exhibits a measured 1 dB bandwidth of ∼51 GHz, ranging from 16 to 67 GHz with an insertion loss of 3.6 dB at 30 GHz. The measured isolation is also better than 22 dB. The measured power handling capability can achieve a 1 dB compression point at an input power of 23.8 dBm at 30 GHz with a negative body bias, and the simulation result shows a 1 dB compression point nearly 24 dBm. Based on the proposed model, the large-signal performances under different body biases can be significantly predicted when including the parasitic gate-to-gate capacitance in a dual-gate MOSFET. |

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.
