— This paper presents a small dual-band 0.9GHz /1.8GHz inverse class F power amplifier with load-switch functionality using a single BiCMOS amplifier line-up with a MEMS based reconfigurable matching network. The realized prototype measures 40mm 2 , offers 31dBm with 40% efficiency at 0.9GHz and 30dBm with 34% at 1.8GHz. The load-switch provides up to 10%(More)
—Radio frequency (RF) micro-electro-mechanical systems (MEMS) capacitive switches show great promise for use in wireless communication devices such as mobile phones, but for the successful application of these switches their reliability needs to be demonstrated. One of the main factors that limits the reliability is charge injection in the dielectric layer(More)

A technology platform is described for the integration of low-loss inductors, capacitors, and MEMS capacitors on a high-resistivity Si substrate. Using this platform the board space area taken up by e.g. a DCS PA output impedance matching circuit can be reduced by 50%. The losses of passive components that are induced by the semi-conducting Si substrate can(More)
We present a novel, fast, and cost-effective method to measure the capacitance-voltage relation of an electronic device. Capacitances are determined using a single-frequency 1-port S-parameter setup constructed from discrete components. A new way is introduced to correct for non-linearities of the used components. C-V curves are measured in less than a(More)
Dielectric, ferroelectric and piezoelectric thin films are getting more and more attention for next generation mobile communication and medical systems. Thin film technologies based on dielectric, ferroelectric and piezoelectric thin films enable system-in-package (SiP) devices, resulting in optimal integration of various functions in one module with(More)
Non-linearities play an important role in micro-and nano-electromechan-ical system (MEMS and NEMS) design. In common electrostatic and magnetic ac-tuators, the forces and voltages can depend in a non-linear way on position, charge, current and magnetic flux. Mechanical spring structures can cause additional non-linearities via material, geometrical and(More)
Due to their atomic-scale thickness, the resonances of 2D material membranes show signatures of nonlinearities at amplitudes of only a few nanometers. While the linear dynamics of membranes is well understood, the exact relation between the nonlinear response and the resonator's material properties has remained elusive. In this work, we propose a method to(More)
