This chapter introduces low-power circuit design focusing on CMOS and FinFET technologies, emphasizing the critical importance of energy efficiency in modern battery-powered devices. It discusses the sources of power dissipation in digital circuits and highlights various low-power design techniques. Also, it outlines the advantages of FinFET technology over traditional CMOS, particularly for smaller technology nodes.
Power consumption in integrated circuits has three components: dynamic power, static power, and short-circuit power.
Multiple techniques exist to reduce power in CMOS circuits, including voltage scaling, clock gating, and power gating.
FinFET technology significantly reduces leakage and improves dynamic performance at scales smaller than 22nm.
The power consumed due to the charging and discharging of capacitors in a circuit during switching.
The power consumed due to leakage current when the circuit is not actively switching.
A type of transistor technology that improves switching performance and reduces leakage current, useful for smaller nodes in circuit design.
A technique used to reduce power consumption by lowering the supply voltage.
A design technique that disconnects the power supply from inactive blocks to save power.
