Tuned Optical Receiver Front Ends
Unified analytical expressions have been derived for calculating the resonant frequencies, transimpedances and equivalent input noise current densities of the four most widely used tuned optical receiver front ends built with FET’s and p-i-n diodes. A more accurate FET model has been used to improve the accuracy of the analysis. The Miller’s capacitance has been taken into account, and its impa...
متن کاملKa-Band SiGe Receiver Front-End MMIC for Transponder Applications
A fully integrated, front-end Ka-band monolithic microwave integrated circuit (MMIC) was developed that houses an LNA (low noise amplifier) stage, a down-conversion stage, and output buffer amplifiers. The MMIC design employs a two-step quadrature down-conversion architecture, illustrated in the figure, which results in improved quality of the down-converted IF quadrature signals. This is due t...
متن کاملA CMOS Analog Front-end Receiver with Desensitization to Input Capacitance for Broadband Optical Wireless Communication
Line-of-sight optical wireless channels are emerging as a promising broadband wireless access technology. This paper describes a front-end transimpedance amplifier (TIA) that is designed to overcome challenges faced by high-speed optical wireless links requiring receivers with wide field-of-view (FOV) and high dynamic range for signal acquisition/tracking. This transimpedance amplifier employs ...
متن کاملA 77 GHz Front-End Receiver for Antenna Arrays
SiGe bipolar technologies have proven to be viable candidates for integrated circuits operating at very high frequencies, due to consistently increasing cutoff frequencies of the transistors. While millimeter wave (MMW) integrated circuits have traditionally been implemented in GaAs or InP, the advancement of silicon technologies has recently enabled silicon-based ICs with promising and cost-ef...
متن کاملA 2.5-THz Receiver Front End for Spaceborne Applications
The OH radical is an important player in known ozone depletion cycles; however, due to its location in the atmosphere, it must be studied from either a balloon or spaceborne platform. For long-term mapping over large portions of the earth, a spaceborne platform is the most desirable. NASA's Earth Observing System Microwave Limb Sounder instrument is slated to house a 2.5-THz Schottky-diode rece...
