Computing circuits suffer from the process, voltage and temperature variations and aging. These factors reduce yield and lifetime of the circuits and therefore limit the advance in modern computing technology. The process variations and aging result in timing failures that often can be resolved by delay matching. However, this strategy requires delay elements which cause additional power cost. We...
Asynchronous circuits will play an important role in microelectronic systems in the future, especially in energy harvesting and autonomous (EHA) systems where such circuits will be able to offer robustness and deliver high efficiency in a wide range of power-energy conditions. The concept of Capacitor Bank Block (CBB) mechanisms was proposed to form the basis of electronics for powering asynchronous...
In future systems with relatively unreliable and unpredictable energy sources such as harvesters, the system Vdd may become non-deterministic. Reliable and accurate on-chip voltage sensors are therefore indispensible for the power and computation management of such systems. Stable and known references are also difficult to obtain in this environment. This paper describes a reference-free voltage sensor...
