Abstract
Various embodiments are disclosed of apparatuses and methods for linearization. A linearized signal can control, for example, a microelectromechanical device, a microelectromechanical device, and/or a device controlling a modulated intensity of electromagnetic energy. Some embodiments include linearization functions such as a logarithm or x/(a+x).
Claims5
Apparatus for linearization of an output signal comprising:
- a first input node adapted to receive an input signal for providing electrostatic control of a micromechanical device, the micromechanical device having a nonlinear response to increasing input signals;
- a correction signal according to the formula x/(a+x), wherein x is a variable and a is a constant;
- and
- an output node for providing an output signal responsive to a combination of the input signal and the correction signal, the output signal providing linearized electrostatic control of the micromechanical device.
