Among all device characteristics, noise can be a particularly challenging and difficult design topic.This article mainly discusses the impact of clock noise on high-speed DAC phase noise. Sources of DAC Phase Noise For high-speed DACs, phase noise primarily comes from the following aspects: clock noise, power supply noise, as well as internal noise and interface … Read more
Protein Hydrolysis Targeted Chimeras (PROTAC) are bringing revolutionary changes to the fields of biology and medicinal chemistry. PROTAC consists of a target protein ligand, an E3 ligase ligand, and a spacer group[Unlike the linker used in antibody-drug conjugates, here we specifically use “spacer” instead of the commonly seen “linker” in PROTAC literature]. PROTAC structural composition … Read more
