This paper presents a novel CMOS low-voltage and low-power positive second-generation current conveyor (CCII+ ). The proposed CCII+ uses two n-channel differential pairs instead of the complementary differential pairs; i.e. (n-channel and p-channel), to realize the input stage. This solution allows almost a rail-to-rail input and output operation; also it reduces the number of current mirrors n...

Simulations of ultra-long (10 mm) semiconductor optical amplifier’s induced optical chirp (cross-phase modulation), with posterior conversion to amplitude modulation by proper filtering, show promising results for wavelength conversion with pulse re-amplifying and re-shaping in 10 Gbps and 20 Gbps. The dependences on filter bandwidth and optical input power (high, medium and low levels) are ana...

This paper presents a reusable, general-purpose, mobile augmented reality (AR) framework developed to address the critical and repetitive challenges specific to visualization in outdoor AR. In all engineering applications of AR developed thus far, basic functionality that supports accurate user registration, maximizes the range of user motion, and enables data input and output has had to be rep...

This paper proposes a pulsed power generator which consists of two types of switched-capacitor booster modules. A doubling mode module employed to elevate the input voltage to a specified level and, constant mode module is used to increase the elevated voltage into the finally intended bipolar output voltage. Also, the proposed modular structure does not utilize any switches across the load. Ot...
