Powering embedded CMOS logic on MEMS-based micro-robots

A hypothetical new digital-design paradigm called Field Programmable Robot Arrays (FPRAs) has been introduced in [1] which raises a number problems that need to be solved for successful implementation. An FPRA combines CMOS reprogrammable logic with micro-robots having constrained motion and sensing capabilities. The goal of the FPRAs is to build digital-logic structures by physical motion as well as the electronic reconfiguration (commonly used in prior programmable logic). In this paper, we present the development of a circuit for powering the digital logic portion of FPRAs. We assume for physical motion the FPRA uses MEMS-based scratch drive actuator (SDA) micro-robots like those developed by Donald et al. [2] as a foundation to build other features needed to develop FPRA. We validate this by developing Verilog-A model of an electrostatic actuator and simulating in Cadence AMS (Analog Mixed Signal) environment.
