Maximizing Efficiency: Low-Power Design Techniques in Digital ICs for Future Innovations
In this article, Kushal Sawarkar, a professional content writer specializing in the semiconductor and electronics industry, discusses low-power design techniques for digital integrated circuits (ICs).
Digital integrated circuits are implemented in a wide range of sectors such as automotive, consumer electronics, and telecommunications. They provide advantages such as being lightweight, small in size, cost-effective, reliable, and easy to replace.
Consegic Business Intelligence predicts that the Digital IC Market will expand significantly, with a projected size of over USD 179.47 Billion by the year 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-growing electronics sector is creating a strong need for digital integrated circuits (ICs) that are energy-efficient and consume less power. New methods and advancements in the industry are focusing on reducing power usage while still achieving high levels of performance and efficiency.
Major strategies in designing low-power systems involve Dynamic Voltage and Frequency Scaling (DVFS). DVFS involves adjusting the voltage and frequency of a processor in real-time according to the workload being processed. By reducing the voltage and frequency during times of low activity, considerable power savings can be achieved. This method is widely utilized in contemporary processors and embedded systems, but it necessitates complex control algorithms to effectively manage performance and power consumption.
Clock gating is a technique that helps reduce power consumption in electronic circuits by turning off the clock signal to parts that are not currently in use. This prevents unnecessary power usage from switching activities. By only allowing active circuit parts to consume power, efficiency is increased. Clock gating can be applied at different levels, such as blocking off entire sections or individual flip-flops.
Power gating is a technique that involves shutting off the power to specific sections of a circuit when they are not actively being used. This helps to decrease the amount of power consumed by the circuit, both when it is in use and when it is in standby mode. To implement power gating successfully, designers need to carefully plan and design power switches and control circuits so that the sections can be quickly powered back on without impacting the circuit's overall performance.
Multi-threshold CMOS is a technology that involves using transistors with varying threshold voltages in a single circuit. This helps to find a middle ground between performance speed and power efficiency. Transistors with high threshold voltages are used to reduce leakage current, while those with low threshold voltages are utilized in areas where fast operation is crucial.
Adiabatic switching is a method that reduces energy loss by charging and discharging capacitors slowly, allowing for the recycling of energy in the circuit. This approach is rooted in reversible computing, which aims to minimize the amount of energy lost during each operation.
Innovations in low-power design have been happening in the industry, with Renesas Electronics introducing third-generation 5G mmWave beamforming ICs that use Dynamic Array Power technology. These advanced ICs can adapt the output power over a wide range, providing flexibility and efficiency for 5G applications.
Incorporating 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 usage. Advanced power management ICs have been introduced for various purposes, such as in automotive and industrial settings. Companies like ROHM have developed small, energy-efficient DC-DC converter ICs that are suitable for consumer electronics.
Current research is centered on improving existing techniques and exploring new materials and transistor designs. One promising example is the multigate technology used in FinFET transistors, which helps reduce leakage currents and improve power efficiency.
In conclusion, the continuous improvement in low-power design strategies for digital integrated circuits is mainly motivated by the growing demand for energy efficiency in a connected world. Progress in dynamic power management, innovative IC structures, and the incorporation of smart systems are setting new standards for the industry, ensuring that upcoming devices will be both high-performance and energy-saving.
