A 50–1600 MHz Wide–Range Digital Duty–Cycle Corrector With Counter–Based Half–Cycle Delay Line

open access: yesIEEE Access, 2023
Duty-cycle distortion may occur due to variations in the process, voltage, and temperature, or if the clock signal passes through clock buffers. To compensate duty-cycle distortion, a digital duty-cycle corrector (DCC) with counter-based half-cycle delay

Duty cycle of 33% increases cardiac output during cardiopulmonary resuscitation.

open access: yesPLoS ONE, 2020
BACKGROUND:The aim of this study was to investigate whether 33% duty cycle increases end-tidal carbon dioxide (ETCO2) level, a surrogate measurement for cardiac output during cardiopulmonary resuscitation (CPR), compared with 50% duty cycle.
