This paper describes a single-ended switch-capacitor harmonic-rejection power amplifier to operate in the 915 MHz ISM band for ZigBee applications. A multipath feed-forward harmonic-rejection technique is employed to suppress the 2nd/3rd/4th harmonics of the switch-capacitor power amplifier (PA) by 48/17/24 dB, respectively. The measured PA peak drain(More)
Modern Systems-on-Chip(SoCs) frequently power-off individual voltage domains to save leakage power across a variety of applications, from large-scale heterogeneous computing to ultra-low power systems in IoT applications. However, the considerable energy stored within the capacitance of the powered-off domain is lost through leakage. In this paper, we(More)
The continued trend toward increased silicon integration in recent years has enabled large, complex SoC systems encompassing an ever-expanding range of capabilities. Maintaining energy-efficient operation continues to be at the heart of high-performance and low-power mobile applications alike, highlighting the crucial role of low-power design methodologies(More)
Recent years have seen the emergence of 3D integration technology. This technology promises significant improvements in cost, capacity, bandwidth and power. The papers in this session will describe three diverse ways of leveraging the third dimension: silicon-interposer based 3D integration, stacked die using a fine-grained standard-cell design style, and(More)
