Abstract
Circuitry for generating AC signals is provided. The circuitry may be used to produce AC drive signals for microelectromechanical systems (MEMS) devices such as MEMS devices used in fiber-optic communications network equipment. The circuitry may include an amplitude controller for producing a DC voltage, a waveform generator for producing an AC waveform having an amplitude proportional to the DC voltage, and a transformer for boosting the AC waveform to produce the AC drive signals.
