Driving Efficiency: Exploring Low-Power Design Techniques in Digital ICs for Energy-Efficient Devices

Efficient methods for reducing power consumption in digital integrated circuits are discussed in this article by KUSHAL SAWARKAR, who is a Professional Content Writer specializing in the Semiconductor and Electronics Industry.

Integrated circuits (ICs) that are digital are utilized in a wide array of industries such as automotive, consumer electronics, and telecommunication. These ICs provide advantages such as being lightweight, small in size, cost-effective, reliable, and easy to replace.

The Digital IC Market is predicted to expand significantly in the coming years, with an estimated value of over USD 179.47 Billion by 2031, up from USD 93.71 Billion in 2022. This growth is expected to continue with an increase of USD 98.79 Billion in 2023, showing a compound annual growth rate (CAGR) of 7.7% from 2023 to 2031, as reported by Consegic Business Intelligence.

The electronics industry is constantly changing and growing, leading to an increased need for digital ICs that use energy efficiently and consume low power. New methods and advancements in the industry are focusing on reducing power usage while still maintaining high performance and efficiency.

Important strategies in designing low-power systems

Dynamic Voltage and Frequency Scaling (DVFS) is a method that changes the voltage and frequency of a processor based on the workload. By reducing the voltage and frequency during times of low activity, it can save a significant amount of power. This technique is frequently used in modern processors and embedded systems, but it requires advanced control algorithms to effectively manage performance and power usage.

Clock gating is a technique used to save power by turning off the clock signal in parts of a circuit that are not being used. This helps reduce power consumption by minimizing unnecessary switching activity. By only allowing active parts of the circuit to consume power, efficiency is improved. Clock gating can be applied at different levels, such as blocking off large sections of the circuit or targeting individual flip-flops.

Power gating is the practice of shutting off power to specific sections of a circuit when they are not being utilized. This technique is effective in reducing both dynamic and leakage power, especially in standby situations. Proper implementation of power gating involves designing power switches and control circuits to allow modules to quickly resume operation without negatively impacting overall performance.

Multi-threshold CMOS is a technology that involves using transistors with various threshold voltages in a single circuit to find a good compromise between speed and power usage. This is done by using high-threshold transistors to reduce leakage current and low-threshold transistors to boost speed in important areas.

Adiabatic switching is a method that reduces energy loss by slowly charging and discharging capacitors in a circuit, allowing energy to be recycled. It is a technique used in reversible computing to minimize the amount of energy lost during operations.

In the field of low-power design, there have been many important advancements and progress. Renesas Electronics has introduced new third-generation 5G mmWave beamforming ICs that incorporate Dynamic Array Power technology. These advanced ICs have the ability to adapt the output power over a wide range of levels, providing great flexibility and efficiency for 5G uses.

Incorporating artificial intelligence into edge devices has led to the creation of power systems that can adjust dynamically using current data, ultimately improving energy efficiency. Various industries have seen the emergence of advanced power management integrated circuits (ICs) that serve a variety of purposes, such as in automotive and industrial settings. Brands like ROHM have developed small and user-friendly energy-saving DC-DC converter ICs for consumer electronics.

Current research is dedicated to improving existing techniques and exploring new materials and transistor designs. One example is the FinFET multigate technology, which has the potential to reduce leakage currents and improve power efficiency.

In summary, the continuous development of methods to reduce power consumption in digital integrated circuits is mainly motivated by the growing demand for energy efficiency in a world where everything is interconnected. Breakthroughs in managing dynamic power, creating new IC designs, and incorporating smart systems are setting higher standards for the industry, ensuring that upcoming devices will be both high-performing and energy-saving.
