Abstract
This paper presents an energy ef ficient successive-ap-
proximation-register (SAR) analog-to-digital converter (ADC)
for biomedical applications. To reduce energy consumption, a
bypass window technique is used to select switching sequences to
skip several conversion steps when the signal is within a prede-
fined small window. The power consumptions of the capacitive
digital-to-analog converter (DAC), latch comparator, and digital
control circuit of the proposed ADC are lower than those of a
conven
