This paper examines the need for and associated challenges and solutions to reduce quiescent current (IQ).
IQ is the no-load quiescent current, and the most important bottleneck to overcome for duty-cycled low-power systems. Low IQ enables longer battery life.
Reducing IQ creates trade-offs in transient noise performance, die package area and output power range.
Reducing IQ by decades without sacrificing performance or area requires a reexamination of both silicon technologies and circuit techniques.
