The tradeoffs of LDO voltage regulator architectures and the advantages of “capless” LDOs are presented below. LDO VOLTAGE REGULATOR ARCHITECTURES A typical LDO voltage regulator consists of a voltage reference, an error amplifier, a pass transistor, and a resistor feedback. The output voltage o...
SK Hynix does something similar with its charge trap CMOS. The company recently introduced a 238-layer circuit that it calls 4D flash. The 4D in this case refers to a chip with a CMOS layer on top of a Peri Under Cell (PUC) layer, which contains the peripheral logic circuit. Accordi...
