We report the flip-chip bonding of a 16/spl times/16 array 970-nm vertical-cavity surface-emitting lasers (VCSELs) to an silicon CMOS driver circuits. The small-signal bandwidth bonded VCSEL is in excess 4 GHz. Individual VCSELs are capable being modulated by circuits at 1 Gb/s. thermal impedance 1/spl deg/C/mW. measured crosstalk suppression between channels approximately 20 dB. Simultaneous parallel testing up 80 Gb/s per demonstrated.
The design, packaging approach, and experimental evaluation of the free-space accelerator for switching terabit networks (FAST-Net) smart-pixel-based optical interconnection prototype are described. FAST-Net is a high-throughput data-switching concept that uses reflective system to globally interconnect multichip array smart pixel devices. three-dimensional links each chip directly every other with dedicated bidirectional parallel data path. in experiments, several smart-pixel devices were...
We present a device concept based on cascaded electro-optic deflection in domain microengineered ferroelectric chip. In our design, large angles are achieved by cascading several smaller scanners single chip, such that each successive scanner stage builds upon the of previous stage. demonstrate basic using two-stage fabricated crystal wafer LiTaO3. By operating specially designed programmable multichannel driver provides ±1.1 kV per stage, total scan angle 25.4° at 5 kHz was demonstrated....
The experimental optical interconnection module of the Free-Space Accelerator for Switching Terabit Networks (FAST-Net) project is described and characterized. Four two-dimensional (2-D) arrays monolithically integrated vertical-cavity surface-emitting lasers (VCSEL's) photodetectors (PD's) were designed, fabricated, incorporated into a folded system that links 10 cm x multichip smart pixel plane to itself in global point-to-point pattern. effects fully connected network which each chip all...
Abstract Recently, human gait pattern has turned into an essential biometric feature to recognize individual remotely. Gait as a becomes challenging owing variation in appearance under different covariate conditions (eg, shoe, surface, haul, viewpoint and attire). The covariates may alter few fragment of while other stay unaltered, leading lower the probability correct identification. To overcome such variation, improved recognition strategy is proposed this article by energy image...
A 'triggered' transimpedance digital optical receiver is described which usable in noisy environments typical of dense mixed-signal circuits. Results show enhanced immunity to supply variations compared conventional receivers.
This work explores the injection locked single and differential ended ring VCO (Voltage Controlled Oscillator) suitable for a frequency synthesizer to operating over wide range of frequencies with reduced phase noise. Along design, comparisons between 3 stage topologies were studied. Single was observed have tuning 1.2 3.6 GHz noise −110.2 dBc/Hz at 10 MHz offset design 1.5 3.1 −109.9 offset. The VCOs designed using 90 nm CMOS technology in ADS (Advance Design System).
Wide tuning range delay cell based 3-stage differential ring VCO designed using 90nm CMOS process operating at 2.6 GHz frequency shows better single event tolerance compared to diode-connected, triode load and Maneatis topologies.

This paper proposes a system-on-chip design to perform run-time reconfiguration using soft-core processor. The reconfigurable module consists of set Processing Elements (PEs) that are fully connected each other through crossbar network. Run-time is achieved by dynamically selecting the desired number PEs based on input data dynamic selection leads optimum resource utilization and lesser power consumption for computationally intensive applications such as media processing. Optimization was...
