Exploring methods to reduce power consumption in digital integrated circuits, written by KUSHAL SAWARKAR, a Professional Content Writer specializing in the Semiconductor and Electronics Industry.
Integrated circuits (ICs) that are digital in nature are utilized in a wide range of industries such as automotive, consumer electronics, and telecommunications. These ICs provide advantages such as being lightweight, compact, cost-effective, reliable, and easy to replace.
Consegic Business Intelligence predicts that the Digital IC Market will see significant growth, with an estimated size of over USD 179.47 Billion by 2031, up from USD 93.71 Billion in 2022. This represents a projected increase of USD 98.79 Billion in 2023, with a compound annual growth rate of 7.7% from 2023 to 2031.
The fast-changing electronics sector is causing a need for digital integrated circuits (ICs) 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.
Important Methods for Reducing Power Consumption
Dynamic Voltage and Frequency Scaling (DVFS) is a technique that adjusts 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, considerable energy savings can be achieved. DVFS is widely used in modern processors and embedded systems, but it requires advanced control algorithms to effectively manage performance and power usage.
Clock gating is a method used to save power by cutting off the clock signal to parts of the circuit that are not being used. This helps reduce the amount of power being used by preventing unnecessary switching. 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 entire sections of the circuit or individual flip-flops.
Power gating is a technique that involves shutting off power to specific parts of a circuit when they are not being used. This method helps to decrease both dynamic and leakage power consumption, which is particularly beneficial during standby modes. Implementing power gating requires the precise design of power switches and control circuits to ensure that components can quickly resume operation without causing any impact on 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 tasks that require high speed.
Adiabatic switching is a method that reduces energy loss in circuits by gradually charging and discharging capacitors, allowing energy to be reused. It is a technique that focuses on reversible computing 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 third-generation 5G mmWave beamforming ICs that use Dynamic Array Power technology. These advanced ICs can efficiently control output power over a wide range, providing great flexibility and efficiency for 5G applications.
The incorporation of artificial intelligence into edge computing has led to the creation of power systems that can make real-time adjustments based on data, improving energy efficiency. Advanced power management ICs are now available for various industries such as automotive and industrial systems. Companies like ROHM have developed small, energy-efficient DC-DC converter ICs suitable for consumer electronics.
Current research is concentrating on improving existing techniques and exploring different materials and transistor designs. 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, innovative IC structures, and incorporation of smart systems are setting higher standards for the industry, ensuring that upcoming devices will be both high-performance and energy-saving.
