Advancing Low-Power Design Techniques in Digital ICs: Industry Developments and Innovations

Methods 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.

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

As per Consegic Business Intelligence, the Digital IC Market is expected to expand significantly, with a projected market size of over USD 179.47 Billion by 2031, up from USD 93.71 Billion in 2022. The market is forecasted to increase by USD 98.79 Billion in 2023, with a compound annual growth rate (CAGR) of 7.7% from 2023 to 2031.

The electronics industry is constantly changing and this has created a need for digital integrated circuits (ICs) that are energy-efficient and consume low power. New methods and advancements in the industry are focused on reducing power while also improving performance and efficiency.

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

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

Power gating is a technique where the power supply to specific sections of a circuit is cut off when they are not being used. This method helps to decrease the amount of power consumed by both active and inactive components, particularly in standby modes. To implement power gating successfully, engineers must design efficient power switches and control circuits that allow modules to transition between sleep and active states quickly without impacting the circuit's overall performance.

Multi-Threshold CMOS is a technology that balances speed and power consumption in a circuit by incorporating transistors with varying threshold voltages. 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 in circuits by slowly charging and discharging capacitors, allowing for the recycling of energy. This approach is grounded in reversible computing, which aims to minimize the amount of energy wasted during operations.

In the field of low-power design, there have been many important advancements and progressions. Renesas Electronics has introduced new 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.

Utilizing artificial intelligence at the edge has led to the creation of power systems that can adapt in real-time based on data, improving energy efficiency. Advanced power management ICs have been introduced to various industries, such as automotive and industrial systems. Brands like ROHM have developed small and user-friendly DC-DC converter ICs that help save energy in consumer electronics.

Current research is concentrating on refining existing techniques and exploring different materials and transistor designs. One promising development is the use of multigate FinFET technology, which has the potential to reduce leakage currents and improve power efficiency.

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