A CMOS Time-to-digital Converter LSI with half-nanosecond resolution by inverter-delay-time has been developed for measuring time intervals of multi-pulse by fully digital circuit. The accuracy is achieved by using digital processing with crystal clock reference 2 MHz, though inverter-delay-time is not stable due to variation of process, temperature and supply voltage. It was confirmed that time...
Recently, waveguides using LiNbO 3 (LN) have been developed for telecommunications. The authors note that the electric field sensor of a LN waveguide is expected to be small, simple and cheap, especially when using a Y-cut LN that has a smaller Pockels constant. No birefringence is expected along with the low temperature dependence of the electro-optic effect. The temperature dependence...
