A 0.13-μm CMOS Dynamically Reconfigurable Charge Pump for Electrostatic MEMS Actuation

FPGA BASED ELECTRONIC CHARGE PUMP FOR SUPER POWER SAVING

OVERVIEW OF EXISTING SYSTEM

Design of FPGA based reconfigurable charge pump for microelectromechanical system (MEMS) electrostatic actuation was designed here. The purpose of the circuit is to generate sufficient on-chip voltages that are continually reconfigurable for MEMS actuation. Small 1-pF pumping capacitors are used to reduce the circuit area. Digitally programmable voltage levels can be outputted by varying the number of stages and the clock drive levels dynamically. Reduced power consumption is achieved using a variable frequency clock. The circuit attains a measured maximum output voltage of 10.1 V from a 1.2 V supply. Its nominal clock is set to 50 MHz.

Proposed System

In the proposed system we are implementing a adiabatic Controller for not only activating the MEMS for a while also it will recycle the wasted energy and store in micro capacitors to enable few digital circuits through that. The concept of adiabatic works well in saving the power consumption too. The advantage of the system is efficient usage of power and compact design architecture for a huge concept.
