— 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)
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)
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)
