Maximizing Efficiency: Low-Power Design Techniques Revolutionizing Digital ICs in the Semiconductor Industry
Strategies for reducing power consumption in digital integrated circuits, written by KUSHAL SAWARKAR, a professional content creator specializing in the semiconductor and electronics sectors.
Integrated circuits (ICs) that are digital in nature are utilized in multiple sectors such as automotive, consumer electronics, and telecommunication. These ICs provide advantages such as being lightweight, small in size, cost-effective, highly reliable, and easy to replace.
Consegic Business Intelligence predicts that the Digital IC Market will see significant growth, with a projected size of over USD 179.47 Billion by 2031, up from USD 93.71 Billion in 2022. The market is expected to increase by USD 98.79 Billion in 2023, with a compound annual growth rate (CAGR) of 7.7% from 2023 to 2031.
The fast-paced electronics sector is creating a strong need for digital integrated circuits that are energy-efficient and consume low power. Various techniques and advancements in the industry are focusing on decreasing power usage while still achieving optimal performance and efficiency.
One important technique in low-power design is Dynamic Voltage and Frequency Scaling (DVFS). This technique involves adjusting the voltage and frequency of a processor in real-time depending on the workload. By lowering the voltage and frequency during times of low activity, significant power savings can be achieved. DVFS is a commonly used method in modern processors and embedded systems, but it requires advanced control algorithms to effectively balance performance and power consumption.
Clock gating is a technique used to lower power consumption by turning off the clock signal to parts of the circuit that are not being used. This helps to reduce unnecessary switching activity and ensures that only active parts of the circuit consume power, making the system more efficient. Clock gating can be implemented at different levels, ranging from blocking off large sections of the circuit to turning off individual flip-flops.
Power gating is a technique that involves shutting off power to specific sections of a circuit when they are not actively being used. This helps to decrease both dynamic and leakage power, making it particularly useful during standby periods. Implementing power gating requires strategic planning of power switches and control circuits to ensure that components can quickly resume operation without impacting the overall performance of the system.
Multi-threshold CMOS is a technique that involves using transistors with varying threshold voltages in a circuit to find a balance between speed and power usage. The use of high-threshold transistors helps reduce leakage current, while low-threshold transistors are utilized in areas where speed is a priority.
Adiabatic switching is a method that reduces energy loss by gradually charging and discharging capacitors, allowing energy to be reused within the circuit. This approach is rooted in reversible computing, which aims to minimize the energy lost during each operation.
In the field of low-power design, there have been many important advancements and progress made recently. Renesas Electronics has introduced innovative third-generation 5G mmWave beamforming ICs that include Dynamic Array Power technology. These advanced ICs can adapt the output power over a wide range of levels, providing great flexibility and efficiency for 5G uses.
The use of artificial intelligence at the edge has led to the creation of power systems that can make changes in real-time based on data, improving power consumption efficiency. Various industries have seen the emergence of advanced power management ICs that serve a wide range of uses, such as in automotive and industrial settings. Businesses like ROHM have developed small and user-friendly energy-saving DC-DC converter ICs for consumer electronics.
New studies are currently concentrating on refining existing techniques and exploring different materials and transistor designs. One promising development is the use of multigate technology in FinFET, which has shown potential in reducing leakage currents and improving power efficiency.
In summary, the continuous improvements in low-power design methods for digital integrated circuits are mainly influenced by the growing demand for energy conservation in a world that is increasingly interconnected. Progress in dynamic power management, unique 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.
