Abstract
Conference Title: 2017 Design, Automation & Test in Europe Conference & Exhibition (DATE) Conference Start Date: 2017, March 27 Conference End Date: 2017, March 31 Conference Location: Lausanne, Switzerland This paper investigates the integration of optoelectronic devices with CMOS to implement reconfigurable threshold logic gates for Boolean functions. The weight of the optoelectronic device can be altered by changing the optical power which is used to reconfigure the threshold logic (TL) gate. These novel reconfigurable gates are called the optoelectronic capacitor based TL (OECTL) gates. The OECTL gates are designed for i) simplistic AND/NAND gates and OR/NOR gates with large fan-in and ii) linearly separable Boolean functions that can be reconfigured to other linearly separable Boolean functions, constrained in reconfiguration by the specifics of TL operation. SPICE simulations in 65nm bulk CMOS technology with a Verilog-A model for the optoelectronic capacitor demonstrate i) AND/NAND gates and OR/NOR gates are 2× faster as fan-in goes above 3 and consumes low power and ii) Boolean functions can be reconfigured with 0.58× smaller delay and 0.46× less power of standard CMOS design.
