This paper presents two variants of a high step-up ratio charge pump for voltage micro electro-mechanical system and condenser microphones. The implementations are based on an additive topology where respectively 46 57 cascaded stages used to generate output 182 V from supply 5 V. pumps have been fabricated in 180 nm SOI process with breakdown more than 200 occupy area 0.52 mm2 0.39 mm2. can up...

Aim of the research is to show developing legitimacy APUD-system lungs in pre and post ontogenesis. Condition neuroendocrine apparatus on rabbits was studied during fetal embryogenesis inner development after 1-180 days birth. Duration chosen according their changing afterbirth features as physiological function organism; selected periods newborn stage, enlightenment, complication locomotion, p...
