AN-1 High voltage amplifiers – How fast are they really?
High voltage amplifier performance in terms of speed is not only determined by the bandwidth and the slew rate, but also by the maximum sustainable current and the capacitance of the load. This article discusses the specifications of high voltage amplifiers required to determine whether they are suitable for a certain amplifier-load combination.

AN-2 Quick and dirty MEMS design
This document contains a number of equations to estimate the order of magnitude of forces, displacements and voltages of MEMS actuators. It can be used in “quick and dirty” MEMS design work. All the functional parts of one- and two-sides clamped beams, comb drives and parallel plate actuators are described. In all cases, bent beams (cantilever and clamped-clamped) are used to define the displacement for a certain force.
