What is Low Power VLSI Design?

An integrated circuit’s overall dynamic and static power consumption can be decreased by using a variety of approaches and processes together referred to as low power design.

The aim of low power VLSI design is to minimize the individual components of power as much as possible, hence decreasing the total power consumption. Switching and short-circuit power make up the dynamic power, whereas leakage current that passes through a transistor makes up the static power.

Why Do We Need Low Power VLSI Design?

Industries are always pushing the envelope with regard to brand-new features and functionality that are all fitted into portable, handheld, and battery-operated products. For such products, increasing battery life by reducing power consumption is a significant differentiator and crucial to the applications used by their end users. In order to provide the end user with a smooth experience and longer battery life, it is equally crucial to reduce the time it takes for a device to transition from the OFF/SLEEP state to the ON/ACTIVE state.

Power consumption is crucial for “plug-in” devices since it can raise system costs by necessitating complex cooling systems and heat sinks by demanding more energy. For instance, when massively parallel computers are used in server firms, a single chip’s power consumption can be significantly reduced because it is used by the whole system. Upgrading these systems with newer, more power-efficient ICs can result in considerable power and cost savings.

Many low-power design methods are available, some of which are relatively user-friendly while others need more effort and complexity.


Power dissipation has evolved into a crucial factor in low-power VLSI circuit designs as a result of the increased use of portable electronic devices and the assessment of microelectronic technology. The circuit complexity and fast speed of evolving VLSI technology imply a large rise in power consumption.
