    Abstract: In this work, we demonstrate via numerical simulation the general design for one dimensional photonic crystal (1D- PC). In the design procedure, the transfer matrix method and Bloch theorem are used to determine the transmission coefficient and dispersion relation of (1D- PC) structure for both TE (transverse electric) and TM (transverse magnetic) ...

    Abstract: In this paper, we report an ultra-low power successive-approximation-register (SAR) analog-to digital converter (ADC) by using a DAC timing strategy with considering overshoot effect to increase the sampling rate. This ADC is simulated for power supplies voltage of 0.6 V and 1.2 V in a 130-nm CMOS technology. The results indicate an ENOB greater th... Show More
