The paper proposes a method to synthesize a digital controller for multiphase switched capacitor converters (SCCs). A specific requirement to the controller is that, regardless of external conditions, it should provide pulses of fixed frequency and width. Asynchronous (self-timed) digital circuits fulfil this requirement by definition. However, their design can be quite complex, especially if an SCC...
This paper proposes a 10 bit fixed window asynchronous Level Crossing ADC that exhibits a power consumption profile proportional to its input signal's rate of change. The ADC utilizes a fixed voltage window, level crossing slope detector to trigger the generation of non uniformly spaced samples that are compared to a ramp voltage for the conversion. The circuit was designed and simulated in a 0.35µm...
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...
