We explore the chiral transmission of electrons across graphene heterojunctions for electronic switching using gate geometry alone. A sequence of gates is used to collimate and orthogonalize the chiral transmission lobes across multiple junctions, resulting in negligible overall current. The resistance of the device is enhanced by several orders of magnitude by biasing the gates into the bipola...

Transmission line pulse (TLP) measurements are used to demonstrate that oxynitride breakdown projections from DC measurements using conventional area and voltage-scaling techniques can be extended to the nanosecond timescale. ESD protection systems can thus be designed to prevent dielectric breakdown. Important concepts in gate dielectric breakdown such as the anode–hole injection model and are...

EEG signals are the signatures of neural activities and are captured by multiple-electrodes and the signals are recorded from pairs of electrodes. To acquire these multichannel signals a low power CMOS circuit was designed and implemented. The design operates in weak inversion region employing sub threshold source coupled logic. A 16 channel differential multiplexer is designed by utilizing a t...

The dynamic and short-circuit power consumption of a complementary metal–oxide–semidconductor (CMOS) gate driving an inductance–capacitance (LC) transmission line as a limiting case of an RLC transmission line is investigated in this paper. Closed-form solutions for the output voltage and shortcircuit power of a CMOS gate driving an LC transmission line are presented. A closed form solution for...

Voltage-tunable plasmon resonances in the two-dimensional electron gas 2DEG of a high electron mobility transistor HEMT fabricated from the InGaAs/InP materials system are reported. The device was fabricated from a commercial HEMT wafer by depositing source and drain contacts using standard photolithography and a semitransparent gate contact that consisted of a 0.5 m period transmission grating...

Most container terminals are still using a bar code system for gate passage of trucks and containers, and also using paper documents (slip) for the delivery of the information on storage location of container in a yard. For this reason, most trucks have to stop at the gate of the container terminals in order to perform several basic jobs. To enhance the productivity of gate management, this stu...

modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. in this paper, a lossy transmission line model of traveling wave switch (twsw) i...

Short Abstract Most industrial digital circuits contain three-state elements besides pure logic gates. We like to presents a gate delay fault test generator for sequential circuits with standard scan design that can handle three-state elements like bus drivers, transmission gates and pulled busses. The delay test pattern generator is based on a well-proved stuck-at test pattern generator that w...
