Maximizing Efficiency: Low-Power Design Techniques for Digital ICs in the Evolving Electronics Industry
Strategies for reducing power consumption in digital integrated circuits 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 wide range of industries such as automotive, consumer electronics, and telecommunication. They provide advantages such as being lightweight, small in size, cost-effective, highly reliable, and easy to replace.
The Digital IC Market is expected to expand significantly, with projections from Consegic Business Intelligence suggesting it could reach a value of over USD 179.47 Billion by 2031, up from USD 93.71 Billion in 2022. This growth is forecasted to continue in 2023, with an increase of USD 98.79 Billion and a compound annual growth rate of 7.7% from 2023 to 2031.
The electronics industry is quickly changing and there is a growing need for digital integrated circuits 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 low-power design is Dynamic Voltage and Frequency Scaling (DVFS). DVFS involves adjusting the voltage and frequency of a processor in real-time according to the workload. By reducing the voltage and frequency during times of low activity, this technique can result in substantial power savings. DVFS is commonly implemented in modern processors and embedded systems, but it requires advanced control algorithms to effectively manage performance and power consumption.
Clock gating is a technique used to save power by turning off the clock signal to parts of a circuit that are not being used. This helps reduce power consumption by stopping unnecessary switching activity. By only allowing active circuit parts to consume power, efficiency is increased. Clock gating can be implemented at different levels, ranging from blocking large sections of the circuit to individual flip-flops.
Power gating is a technique used to save power by 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, particularly in standby modes. Designing power switches and control circuits is essential for successful power gating, as it allows modules to quickly resume operation without impacting overall performance.
Multi-Threshold CMOS is a technology that uses transistors with varying threshold voltages in a single circuit to find a middle ground between speed and power usage. It utilizes high-threshold transistors to reduce leakage current and low-threshold transistors for situations where speed is important.
Adiabatic switching is a method that reduces energy loss by slowly charging and discharging capacitors in order to recycle energy within the circuit. It is a technique that focuses on reversible computing to minimize the energy lost during each operation.
There have been many important advancements in low-power design recently. Renesas Electronics has introduced third-generation 5G mmWave beamforming ICs with Dynamic Array Power technology. These ICs can adjust output power efficiently over a wide range, providing flexibility and efficiency for 5G applications.
Incorporating artificial intelligence into edge devices has led to the creation of power systems that can adapt in real-time, improving energy efficiency. Various industries have seen the emergence of advanced power management chips that serve a variety of applications, such as automotive and industrial systems. Brands like ROHM have developed small DC-DC converter chips that are energy-efficient and suitable for consumer electronics.
New studies have been concentrating on refining existing techniques and exploring different materials and transistor designs. One example is the multigate technology known as FinFET, which has the potential to reduce leakage currents and improve overall power efficiency.
In conclusion, the continuous improvements in low-power design methods for digital integrated circuits are mainly motivated by the growing demand for energy-efficient technology in a connected society. Progress in dynamic power control, unique IC structures, and incorporation of smart systems are setting higher standards for the industry, ensuring that upcoming devices will be capable and eco-friendly.
