Exploring Advanced Low-Power Design Techniques in Digital ICs: Driving Efficiency and Innovation in the Semiconductor Industry

Techniques for designing digital integrated circuits with low power consumption are discussed in this article by KUSHAL SAWARKAR, a Professional Content Writer specializing in the Semiconductor and Electronics Industry.

Digital integrated circuits (ICs) are utilized in a variety of industries such as automotive, consumer electronics, and telecommunications. They provide advantages such as being lightweight, compact, affordable, reliable, and easy to replace.

As stated by Consegic Business Intelligence, the Digital IC Market is expected to expand significantly, with a projected size of over USD 179.47 Billion by 2031, up from USD 93.71 Billion in 2022. This growth is anticipated to continue with an increase of USD 98.79 Billion in 2023, maintaining a compound annual growth rate of 7.7% from 2023 to 2031.

The fast-changing electronics sector is increasing the need for digital ICs that are energy-efficient and consume low power. New methods and advancements in the industry are focusing on reducing power usage while still achieving high performance and efficiency.

One important technique in designing low-power systems is Dynamic Voltage and Frequency Scaling (DVFS). DVFS involves adjusting the voltage and frequency of a processor in real-time depending on the workload. By reducing the voltage and frequency during times of low activity, significant power savings can be achieved. This technique is commonly utilized in modern processors and embedded systems, but it requires advanced control algorithms to effectively manage the balance between performance and power consumption.

Clock gating is a method that helps to reduce power consumption in a circuit by turning off the clock signal to parts of the circuit that are not actively being used. This prevents unnecessary switching and ensures that only the parts of the circuit that are in use consume power, making the circuit more efficient. Clock gating can be implemented at different levels, either by blocking off larger sections of the circuit or by focusing on individual flip-flops.

Power gating is a technique that involves shutting off power to specific parts of a circuit when they are not actively being used. This helps to decrease both dynamic and leakage power consumption, particularly when the circuit is in standby mode. Effective power gating entails designing power switches and control circuits in a way that allows modules to quickly resume operation without impacting overall performance.

Multi-threshold CMOS technology involves using transistors with varying threshold voltages in a circuit to optimize both speed and power efficiency. High-threshold transistors are utilized to reduce leakage current, while low-threshold transistors are employed in areas where speed is a priority.

Adiabatic switching is a method that reduces energy loss by gradually charging and discharging capacitors in order to reuse energy in the circuit. It is a technique that focuses on reversible computing to minimize the energy lost during each operation.

New developments in designing low-power technology have been made recently. Renesas Electronics has introduced third-generation 5G mmWave beamforming ICs that incorporate Dynamic Array Power technology. These advanced ICs can adapt the output power over a broad 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 make real-time adjustments based on data, improving energy efficiency. Advanced power management integrated circuits (ICs) are now available for various uses, such as in cars and industrial equipment. ROHM and other companies have developed small and user-friendly DC-DC converter ICs for consumer electronics.

New studies are currently concentrating on improving existing techniques and exploring different materials and transistor designs. One example is the use of FinFET multigate technology, which has the potential to reduce leakage currents and improve power efficiency.

In summary, the continuous development of low-power design methods for digital integrated circuits is mainly influenced by the growing demand for energy efficiency in a connected society. Progress in dynamic power management, new IC structures, and the incorporation of smart systems are setting new standards for the industry, ensuring that upcoming devices will be both high-performing and energy-saving.
