چکیده
This letter presents a highly integrated power amplifier (PA) antenna with the capability of frequency tuning. A planar inverted-F (PIFA) is used to directly match PA transistor. mitigates lossy output matching network in PA-integrated (PAIA). In order achieve wide tuning range, combination capacitors loaded at PIFA control input impedances so that can be maintained The analysis and design procedure tunable PAIA are detailed. For verification, prototype designed, fabricated, measured. experimental results show range proposed covers from 2 4 GHz. Over this effective isotropic radiation power-added efficiency higher than 40.5 dBm 60% 26.5 dBm, respectively.

A CMOS Transconductance Amplifier Architecture With Wide Tuning Range for Very Low Frequency Applications
A pseudodifferential CMOS operational transconductance amplifier (OTA) with wide tuning range and large input voltage swing has been designed for very small ’s (of the order of a few nanoamperes per volt). The OTA is based on a modified four-quadrant multiplier architecture with current division. A common-mode feedback circuit (CMFB) structure has been proposed and designed using floating-gate ...
متن کاملFrequency Compensated Lc Networks for Oscillators with the Wide Tuning Range
Anyone who have designed a capacitively tuned VFO/VCO with the wide tuning range (>1.5-2x) has noticed that the oscillation threshold changes substantially with the tuning frequency. The usual solution to the problem is a combination of: 1. the AGC circuit, most frequently via the amplifier bias that changes the amplifier conduction angle; 2. shunting the LC circuit with a damping resistor or b...
متن کاملWide range tuning of resonant frequency for a vortex core in a regular triangle magnet
A magnetic vortex structure stabilized in a micron or nano-sized ferromagnetic disk has a strong potential as a unit cell for spin-based nano-electronic devices because of negligible magnetostatic interaction and superior thermal stability. Moreover, various intriguing fundamental physics such as bloch point reversal and symmetry breaking can be induced in the dynamical behaviors in the magneti...
متن کاملDevelopment of a Wide-Tuning-Range Two-Parallel-Plate Tunable Capacitor for Integrated Wireless Communication Systems
This paper reports on the development of a micromachined parallel-plate tunable capacitor with a wide tuning range. Different from conventional two-parallel-plate tunable capacitors, this tunable capacitor consists of one suspended top plate and two fixed bottom plates. One fixed plate and the top plate form a variable capacitor, while the other one provides necessary electrostatic actuation. A...
متن کاملSpontaneous otoacoustic emissions, threshold microstructure, and psychophysical tuning over a wide frequency range in humans.
Hearing thresholds have been shown to exhibit periodic minima and maxima, a pattern known as threshold microstructure. Microstructure has previously been linked to spontaneous otoacoustic emissions (SOAEs) and normal cochlear function. However, SOAEs at high frequencies (>4 kHz) have been associated with hearing loss or cochlear pathology in some reports. Microstructure would not be expected ne...
