I am searching data on how to design variable capacitance using MEMS technology for high frequency circuits. what can be achieved with MEMS technology in terms of linearity, Q factor, operating frequencies, capacitance ratio ... for variable capacitance ? Please, can you bring me some help. -- ___________________________________________ Samuel ROUSSELIN RF Engineer Mobile Multimedia dept CANON Research Centre France S.A.
