Near-threshold computing (NTC) is a promising approach to address the increasing demand for energy efficiency in computing platforms. In NTC, the supply voltage is scaled down to realize quadratic energy savings while degrading the operating frequenc

Near-threshold operation offers energy efficiency at the expense of increased performance variability. Adaptive Voltage/Frequency Scaling (AVS/AFS) techniques can be used to mitigate performance variability, yet their impact on energy efficiency has

Bang-Bang Phase Locked Loops (BB-PLLs) exhibit a nonlinear response that is dependent on the magnitude of the phase error. This paper presents a novel Digital Loop Filter (DLF) with coefficients that adapt to the relative magnitude of the phase error

Bang-Bang phase locked loops (BB-PLLs) offer a low power implementation of digital PLLs. However, the response of BB-PLLs, unlike linear PLLs, depends on the magnitude of the phase error, and thus, exhibits hard nonlinearity. This paper presents a ge

In this paper, an efficient ultra-low-voltage PMU working for TEG input voltages as low as 200mV is proposed. The PMU core, charging an energy buffer, employs a main DC/DC converter. It consists of a cascade of two Dickson-based charge pumps with a v

For energy harvesting applications, a power management unit (PMU) architecture operating at low input voltages is required. The most critical sub-blocks of such a PMU are the voltage multiplier and the low-voltage clock generator. An ultra-low-voltag
