optimization techniques are discussed using digital logic network using threshold logic. Almost same energy consumption changing speedup is possible using threshold network and many complex functions can be implemented using threshold logic with lesser number of logic gate and logic level for which these optimization techniques becomes popular for digital system design and applications. In this...

Electronic control of microwave antennas and circuits is usually based on the use of reverse biased semiconductor junctions. Optical control of such circuits has been by directly illuminating the active (depletion) regions of the semiconductor junctions. In this paper we report indirect optical control of microwave antennas and circuits using a photovoltaic array that generates a light dependen...

A new voltage-programmed pixel circuit using soluble-processed organic thin film transistors (OTFTs) for an active matrix organic light emitting diode (AMOLED) is proposed. The proposed circuit is composed of four switching TFTs, one driving TFT and one storage capacitor, which is simulated by HSPICE. The proposed circuit can compensate for the non-uniformity of OLED current caused by the thres...

A simple fourth-order hyperchaotic circuit with damped harmonic oscillators is described. ANP3 and PSpice simulations including an eigenvalue study of the linearized Jacobian are presented together with a hardware implementation. The circuit contains two inductors with series resistance. two ideal capacitors and one non-linear active conductor. The Lyapunov exponents are presented to confirm th...

We demonstrate a scalable and reconfigurable optical directed-logic architecture consisting of a regular array of integrated optical switches based on microring resonators. The switches are controlled by electrical input logic signals through embedded p-i-n junctions. The circuit can be reconfigured to perform any combinational logic operation by thermally tuning the operation modes of the swit...

We have designed three ASICs for possible applications in a new pixel layer (Insertable B-Layer or IBL) for the ATLAS detector for the first phase of the LHC luminosity upgrade. The ASICs are a high-speed driver for the VCSEL (VerticalCavity Surface-Emitting Laser), a receiver/decoder to decode the signal received at the PIN diode to extract the data and clock, and a clock multiplier to produce...

In this paper a circuit design technique to improve noise tolerant of a new CMOS domino logic family called feedthrough logic is presented. The feedthrough logic improves the performance of arithmetic circuit as compared to static CMOS and domino logic but its noise tolerant is very less. A 2-input NAND gate is designed by the proposed technique. The ANTE (average noise threshold energy) metric...

In very high performance designs, dynamic circuits, such as Domino Logic, are used because of their high speed. Skewed logic circuits can be used to achieve designs having performance comparable to that of Domino but with better scalability. Moreover, a selective clocking scheme may be applied to enhance the power savings for skewed logic circuits. This paper proposes Selectively Clocked Skewed...

 The DSCH program is a logic editor and simulator designed by a research group under the leadership of E.Sicard, a professor of INSA of Toulouse . DSCH is used to validate the architecture of the logic circuit before the microelectronics design is started. DSCH provides a user-friendly environment for hierarchical logic design, and fast simulation with delay analysis, which allows the design a...

– Four different dynamic circuit techniques are proposed in this paper for lowering the active mode power consumption, increasing the speed, enhancing the noise immunity, and reducing the subthreshold leakage energy of domino logic circuits. A variable threshold voltage keeper circuit technique is proposed for simultaneous power reduction and speed enhancement of domino logic circuits. The thre...
