A true-1-V 300-μW CMOS-subthreshold log-domain hearing-aid-on-chip.

This paper presents a true very low-voltage low-power complete analog hearing-aid system-on-chip as a demonstrator of novel analog CMOS circuit techniques based on log companding processing and using MOS transistors operating in subthreshold. Low-voltage circuit implementations are given for all of...
