Photovoltaic (PV) antennas are used as both directcurrent power source and radio-frequency radiator or receptor, resulting in a smarter integrated wireless system. Antenna designs and power management schemes for outdoor and indoor environments are proposed and compared. A dipole and a loop antenna based on amorphous-silicon PV cells were designed for(More)
Single-grain (SG) thin-film transistors (TFTs) fabricated inside location-controlled silicon grains using the -Czochralski method are benchmarked for analog and RF applications. Each silicon grain is defined by excimer laser recrystallization of polysilicon. Thin-film transistors may be fabricated in this manner on silicon or low-cost flexible plastic(More)
Low-complexity, low power UWB radios are required for low data rate short-range applications. FM-UWB is a constant-envelope UWB communication system using double FM: digital FSK followed by high modulation index analog FM to create a constant-envelope signal. The system is intended for low data rate (< 250 kbps), short-range (< 10 m) personal area network(More)
