Patent ID: 10854411

Abstract:
A microelectromechanical systems (MEMS) switching circuit and related apparatus is provided. A MEMS apparatus includes a MEMS switching circuit and a control circuit. The MEMS switching circuit includes a first number of MEMS switches, each configured to close and open based on a high driving voltage and a low driving voltage, respectively. The MEMS switching circuit includes a MEMS-based driver circuit configured to receive a second number of control signals that collectively identify a selected MEMS switch among the first number of MEMS switches. Accordingly, the MEMS-based driver circuit decodes the second number of control signals and causes the selected MEMS switch to close. By using a lesser number of control signals to control a larger number of MEMS switches, it may be possible to reduce control lines between the control circuit and the MEMS switching circuit, thus helping to reduce routing complexity and footprint of the MEMS apparatus.
