“…When the power consumption of the system is smaller than the transmitted power gain, the AIMS is power efficient. Since the reflectometer is a passive device and the reconfigurable impedance matching network can be implemented with MEMS or CMOS switches [1], [3], [5], [10], which consumes almost no static power, the overall AIMS power consumption is to supply the power detectors and digital signal processing. Therefore, the power consumption of the power detectors has a significant contribution on the system's efficiency.…”

This paper presents the design of a CMOS RF RMS power detector for an Automatic Impedance Matching System. The power detector requirements for this application, in terms of dynamic range, resolution, settling time and power consumption, are met by distributing the dynamic range over three power detection units. The appropriate unit is dynamically selected based on the input power range. The output of the detector is digital and linear-in-decibel. The selectors and detection units have been designed in 0.13-μm CMOS technology. Circuit-level simulation results show a dynamic range of 27 dB for input frequencies extending from 800 MHz to 8.5 GHz. The sensitivity of the power detector is −27 dBm, the settling time is less than 12 μs and the power consumption is 1.2 mW.

“…Reconfigurable tuners have also been demonstrated [5][6][7] and not only find applications in reconfigurable transceivers, but can also be utilized as characterization modules for RF devices and circuits. As a variable impedance matching network at the input of a low noise amplifier, a reconfigurable tuner can provide optimum source impedance for minimum noise figure, maximum gain, or maximum linearity at multiple operating frequency bands.…”

An integrated reconfigurable tuner based on a 4-mm long coplanar waveguide transmission line (CPW) loaded periodically with switched capacitors is demonstrated in a standard 45nm CMOS Silicon on insulator (SOI) technology. The tuner is designed with 10 switchable capacitors controlled by a series-in parallel-out shift register, that allows on-the-fly programming, leading to a large Smith chart coverage at 2 GHz with 1024 unique impedance points. The total area of the tuner is 4.4 ×0.42 mm 2 including DC and RF pads.

“…The tunability property is also known as reconfigurability characteristic. Reconfigurable devices such as antennas [1][2][3][4][5][6][7][8][9][10][11][12][13][14], filters [15][16][17][18][19], impedance tuners [20][21][22][23], phase shifters [24,25] and amplifiers [26][27][28][29] have been used in recent years, considerably. The pattern, polarization, bandwidth and resonant frequency are fixed radiation parameters of the conventionally used antennas.…”

Abstract-A novel multi-state RF MEMS switch for microstrip antenna applications is presented. The proposed switch exhibits seven different states of operation, has a very simple DC biasing mechanism, and can be integrated with antenna structure. Based on these properties, this switch may find its usage in multifunction reconfigurable antennas. To exhibit this application, it is employed in the reconfiguration mechanism of a U-slotted antenna. In different states of the switch, the antenna resonates at different frequencies. All the standard frequency bands of the wireless communication services with some additional frequency bands is covered with this reconfigurable U-slotted antenna. Moreover, the proposed antenna structure is a cost-effective solution since it comprises a commonly used FR4 substrate. The switch is integrated with antenna structure on the same substrate. A prototype of the designed antenna was fabricated and tested for performance verification of the proposed switch and antenna.
