Lasers blink through silicon chips

Researchers have tried for years to use light to carry data because it's much faster and efficient than current interconnections used in telecommunications and computers. Now, engineers at the University of Texas at Austin have designed a chip made of silicon 'photonic crystals'. This chip acts as a silicon modulator...

GA-Based Optimization of Sigma-Delta Modulators for Wireless Transceivers

Over-sampling sigma-delta Analog-to-Digital Converters ADCs are one of the key building blocks of state of the art wireless transceivers. In sigma-delta modulator design, the scaling coefficients determine the peak signal-to-noise ratio. Therefore, selecting the optimum value of the coefficient is very important. To this end, this paper addresses the design...

Current-Mode Modeling for Peak, Valley and Emulated Control Methods

Current-mode operation: An ideal current-mode converter is only dependent on the dc or average inductor current. The inner current loop turns the inductor into a voltage-controlled current source, effectively removing the inductor from the outer voltage control loop at dc and low frequency. The modulator gain is dependent on the...
