The application of circular aperture frequency selective surface (FSS) for the enhancement of electromagnetic performance of monolithic half-wave radome is presented. The performance parameters of the circular aperture type FSS embedded radome panel are computed based on equivalent transmission line method in conjunction with equivalent circuit method (ECM). The EM analysis shows that the circu...

Monolithic GaN High Electron Mobility Transistor (HEMT)-integrated circuits are a promising application of wide band-gap materials. To date, most GaN-based devices behave as NMOS-like transistors. As only NMOS HEMT is currently commercially available, its control circuit requires special design if monolithic integration desired. This article analyzes the schematics comparator, and three compara...

This paper describes a CMOS capacitive sensing amplifier for a monolithic MEMS accelerometer fabricated by post-CMOS surface micromachining. This chopper stabilized amplifier employs capacitance matching with optimal transistor sizing to minimize sensor noise floor. Offsets due to sensor and circuit are reduced by ac offset calibration and dc offset cancellation based on a differential differen...

Knowledge of the temporal and spatial distribution of water vapor and liquid water in the troposphere is fundamental for shortand medium-range prediction of precipitation and severe weather. Current measurements of these quantities in the troposphere are limited by optical extinction in clouds (lidar), in temporal resolution (radiosondes), in spatial resolution (GPS networks) and in spatial cov...
