Power consumption and heat generation in CMOS-based ICs are the dominating factors affecting the system's performance and reliability. Many power reduction techniques, e.g., supply voltage scaling, implementing smaller transistors, limiting switching activity, are well known in public. Supply and threshold voltage scaling is among one of the most efficient methods for reducing power. In addition, process technology designed with transistors optimized for subthreshold operation is a more fundamental path to conserve the low power characteristic of the system. To demonstrate the significance of the process, a series of digital circuits were fabricated using MIT Lincoln Lab's 90nm XLP FDSOI CMOS process with novel transistor technology optimized for 300 mV supply voltage. The circuits include synchronous ring oscillator, synchronous FIR filter, asynchronous ring oscillator, asynchronous FIR filter, and homogeneous parallel asynchronous platform.
