Low Power, Low Area Digital Modulators using Gate Diffusion Input Technique

Journal of King Saud University: Engineering Sciences, 2019
Audio playback devices like IPODs and MP3 players use Sigma Delta Digital to Analog Converters (DACs) where the size and power consumption is of prime importance. Digital modulator is the most important part of Sigma Delta DACs. This paper presents a new

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

FEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.
