II. The Evolution of Low Voltage Computing

Once upon a time, in the early days of computing, giants roamed the earth. Computers like the ENIAC, colossal in stature, feasting on kilowatts of power (Akera, 2007). It was the dawn of an era, yet something needed to change. The computer industry yearned for a Goldilocks solution, powerful yet efficient, not too big, not too power-hungry, just right.

Fast forward to the 21st century, where our digital devices have slimmed down to pocket-sized proportions. Today, it's all about doing more with less. Your smartphone, my friend, is a testament to the triumph of miniaturization and power efficiency. In fact, it operates in a power environment far lower than those early computing leviathans could ever dream of (Isaacson, 2014).

But what sparked this evolution?

The key player in this epic was Moore's Law, the prophetic observation by Intel's co-founder, Gordon Moore, that the number of transistors on a chip would double roughly every two years (Moore, 1965). Yet, even Moore himself didn't foresee that as transistors shrank, the voltage needed to operate them would shrink too. The relentless march of technological progress saw advancements like reduced operating voltages, lower-leakage transistors, and more energy-efficient architectures taking center stage (Hennessy & Patterson, 2011).

This evolution has now birthed the era of low-voltage computing. Fueled by innovation and necessity, it is the cutting edge of our quest for ever-greater power efficiency, a dream sparked by those early computing pioneers, now nestled in the palm of your hand.

Oh, the why of low voltage computing. It's a bit like asking why we breathe air. The benefits are tangible, and the drivers, well, they're as compelling as a cliffhanger at the end of your favorite series' season. Let's unravel this yarn together, shall we?

First off, energy efficiency and sustainability are more than just buzzwords. They're the rallying cries of our generation, the pillars of a future we're carefully crafting (IPCC, 2018). Just like a crafty magician pulling rabbits out of hats, low voltage computing lets us conjure those coveted 1s and 0s while sipping, not gulping, power. In a world rightfully obsessed with reducing carbon footprints, every saved watt counts (Patterson, 2010).

III. Why Low Voltage Computing: Benefits and Drivers

Next, the sweet siren song of cost reduction. Ah, the allure of saving a penny or a thousand. Operating at lower voltages means less electricity consumed, and therefore less spending on energy bills (Shehabi et al., 2016). It's simple math, really. It's like getting the same delicious doughnut for a cheaper price; it just tastes better.

Then there's the appeal of increased device longevity. Like a vintage wine, devices powered by low voltage tech just seem to get better with time. The lower the power, the less heat generated, which in turn helps to slow the aging process of the components (Mudge, 2001). It's like a digital fountain of youth, keeping your devices kicking longer.

Finally, regulatory incentives and policy changes are pressing the pedal to the metal, driving this transformation with increasing urgency. Governments worldwide are tightening regulations, pushing industries to reduce their power consumption (European Commission, 2019). They're playing a vital role in ushering in the era of low voltage computing, like the tide carrying in a new day.

So, you see, the reasons for embracing low voltage computing are as compelling as the end credits rolling on a binge-worthy show. It's an inevitability, and, quite frankly, a necessity.

New power-sipping technologies like magnetoresistive random-access memory (MRAM) are making waves in the industry, allowing our devices to remember more while forgetting their power-hungry past (Kim et al., 2020).

Software, too, has been training for this low voltage marathon. From energy-aware task scheduling algorithms to power-optimized compiler techniques, the world of code has learned to make every joule count (Hofmann et al., 2002). It's like a master chef, meticulously using every ingredient to create a gourmet dish.

Next up are the breakthroughs in semiconductor materials. Enter gallium nitride (GaN) and silicon carbide (SiC). These wonder materials have demonstrated fantastic potential for operating at low voltages while maintaining high performance, like athletes breaking world records while barely breaking a sweat (Chowdhury et al., 2018).

And then, there's quantum computing, the enigmatic newcomer. It promises to completely upend our notions of computing. Quantum bits, or qubits, operate in a realm far removed from our classical binary systems, offering the tantalizing potential for massive computational power at a fraction of the energy cost (Hollenberg et al., 2017).

Each of these components – hardware, software, materials, and quantum phenomena – are like pieces of an intricate puzzle. Together, they're crafting the future of low voltage computing. And that, my friend, is an exciting future indeed.
