Novel micromirror design with variable pull-in voltage [PDF]

open access: yesMicroelectronic Engineering, 2010
A novel micromirror is presented having a variable pull-in voltage. This allows analog Pulse Width Modulation (PWM) so that the number of grey levels is not limited by the number of subframes or bitplanes. The levels can be chosen arbitrarily, allowing less severe speed requirements for the electronic layer below the MEMS, less image processing ...

A Comprehensive Mixed-Mode Time-Domain Load- and Source-Pull Measurement System [PDF]

open access: yes, 2010
We present a novel test set devised for nonlinear balanced device characterization using load-pull techniques. The system is capable of measuring the voltage and current waveforms at the calibration reference planes while independently tuning the device ...

Dynamic Pull-In and Switching for Sub-Pull-In Voltage Electrostatic Actuation

open access: yesTRANSDUCERS 2007 - 2007 International Solid-State Sensors, Actuators and Microsystems Conference, 2007
We propose and experimentally demonstrate a new MEMS switching technique using elastic potential energy to drive switching with electrostatic force used for switch control. This approach allows switching into pulled-in states at voltages significantly less than the quasi-static pull-in voltage.

An approach to harmonic load- and source-pull measurements for high-efficiency PA design [PDF]

open access: yes, 2004
High-efficiency power-amplifier design requires numerous efforts to investigate both input and output harmonic terminations effects. A simplified theoretical approach to clarify the relevance of such terminations is presented here, and design criteria to
