Maximizing Efficiency: Low-Power Design Techniques Revolutionizing Digital ICs

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 different sectors such as automotive, consumer electronics, and telecommunications. They bring advantages such as being lightweight, small in size, affordable, reliable, and easy to replace.

Consegic Business Intelligence predicts that the Digital IC Market will expand significantly, reaching a value 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 growth of the electronics sector is creating a strong need for digital Integrated Circuits (ICs) that are energy-efficient and consume low power. New methods and advancements in the industry are focusing on decreasing power usage while still achieving optimal performance and efficiency.

Important methods in designing low-power systems

Dynamic Voltage and Frequency Scaling (DVFS) is a technique that changes the voltage and frequency of a processor in real-time according to the workload. By reducing the voltage and frequency when the processor is not being heavily used, significant energy savings can be achieved. DVFS is a common practice 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 decrease dynamic power consumption by turning off the clock signal to parts of the circuit that are not being used. This helps to prevent unnecessary switching activity and ensures that only active circuit components consume power, improving efficiency. Clock gating can be applied at different levels, such as blocking at the block level or more detailed gating at the flip-flop level.

Power gating is a technique that involves shutting off power to specific parts of a circuit when they are not being used. This helps to lower both dynamic and leakage power consumption, particularly in standby modes. To implement power gating successfully, designers need to carefully create power switches and control circuits that allow modules to be quickly reactivated without impacting the overall performance of the system.

Multi-Threshold CMOS is a technology that uses transistors with varying threshold voltages in a circuit to find a compromise between speed and power usage. It employs high-threshold transistors to reduce leakage current and low-threshold transistors where speed is important.

Adiabatic switching is a method that reduces energy loss by gradually charging and discharging capacitors, allowing energy to be reused in 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 progressions recently. Renesas Electronics has introduced new third-generation 5G mmWave beamforming ICs that utilize Dynamic Array Power technology. These advanced ICs are able to adapt the output power to various levels, providing flexibility and efficiency for 5G applications.

The implementation of artificial intelligence at the edge has led to the creation of power systems that can adapt in real-time based on data, improving power usage efficiency. The market has seen the emergence of advanced power management integrated circuits (ICs) that serve various industries such as automotive and industrial sectors. For example, ROHM has developed small and user-friendly DC-DC converter ICs that help save energy in consumer electronics.

New studies are currently concentrating on refining existing techniques and exploring different materials and designs for transistors. One example is the FinFET multigate technology, which is showing potential in reducing leakage currents and improving power efficiency.

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