This paper presents a low-power automatic supply multiplexer for reconfigurable step-up/down switching DC-DC converters. The multiplexer continuously compares the input and the output voltages. It then tracks and selects the higher voltage to be used for substrate biasing and supplying gate drivers. This reduces leakage current through substrate diodes and also reduces conduction losses of the driven...
Terahertz radiations, which have a frequency range between 100 GHz and 30 THz, have applications in many fields, including nanotechnology, and photonics1. The use of femto-second laser pulses and a gallium arsenide photoconductive switch (PCSS) to generate THz radiations is well known. THz radiation waves occur when the signal generated in the substrate moves along the PCSS material (which acts as...
The study of a printed zigzag antenna on a high resistivity silicon substrate is presented. The compact on chip antenna allows for length reduction over the traditional half wave dipole by approximately 10%. The antenna operates at 10 GHz, and by micromachining a quarter of the physical length of the antenna on 2mm2 SiO2 membrane using dry etch techniques, an increase in the resonant frequency of...
The study of a 10 GHz miniaturized printed antenna using a high resistivity silicon substrate is presented. The choice of antenna is a meandered dipole, with a length of 4.25 mm, allowing a reduction of the chip area to (5 ?? 4) mm2. By etching the silicon substrate using DRIE-etching techniques, a (1.4 ?? 1.4) mm2 membrane was fabricated for sensing purposes and to enhance the impedance matching...
A top-down detail design of a 5 GHz micro strip coupled line band pass filter in LTCC is presented in this paper. LTCC, which stands for low temperature co-fired ceramic is especially used for wireless and high-frequency applications. Now, the importance of LTCC is becoming more prominent in views of the fact a lot organizations has been funding R&D-projects regarding this new technology that...
As substrates for microelectronic devices, LTCC tape must have excellent combination of dielectric and thermal properties. This paper reports the grain size effect on the dielectric and thermal performance of alumina based LTCC tape. LTCC tape was prepared using tape-casting technique, then fired up to 850degC. The dielectric and thermal performance of the fired LTCC tape was carried out using impedance...
