Acetals derived from racemic 1,3-alkanediols undergo kinetic resolution in chiral oxazaborolidinone-mediated ring-cleavage reaction with nucleophiles such as enol silanes and allylic silanes. Enantioselectivity of the reaction is affected by nucleoph

We have developed a fully logic-MOS-transistor designed on-chip digitally controlled LDO in 40 nm CMOS. The proposed TDC-based voltage sensor used as an ADC can reduce the offset error almost to zero. The area of this LDO with no analog circuits is o

We propose a dynamic voltage-drop sensor, which is fully digital so that it is easy to design into products and use for testing. The 2.4K-gate GHz sensor exploits the difference in the voltage sensitivity between two paths composed of different types

A fast transient-response digital low-dropout (LDO) voltage regulator comprising only low-voltage MOS transistors was developed. The input voltage can be higher than the withstand voltage of the low-voltage MOS transistors by the proposed withstand-v

A technique for controlling rush current and wake-up time of thick-gate-oxide power switches is described. Suppressing the variation of rush current on PVT allows shorter wake-up times, which can reduce leakage currents in a mobile processor. Wake-up

The bodies of partially depleted SOI devices are selectively biased so that circuits operate at low supply voltages without area overhead. Applying forward body bias to logic gates reduces delay variation by 7-21%. A level shifter (LF) and data reten
