We demonstrate the novel and compact implementation of literal gates with one literal window and two literal windows using only resonant tunneling diodes (RTDs). The proposed circuit consists of only three RTDs and one resistor for one literal window and four RTDs and one resistor for two literal windows, with the configuration of a series-connected RTD pair and a series-connected RTD and a res...

Abstract A new configuration for realizing high input impedance voltagemode biquadratic filters with two inputs and one output is presented. The proposed configuration uses two second generation current conveyors (CCII’s) of different polarity, two resistors, and two capacitors. The present configuration is capable of realizing band pass (BP), all pass (AP), and notch filter functions. The circ...

An interfacing circuit for piezoresistive pressure sensors based on CMOS current conveyors is presented. The main advantages of the proposed interfacing circuit include the use of a single piezoresistor, the capability of offset compensation, and a versatile current-mode configuration, with current output and current or voltage input. Experimental tests confirm linear relation of output voltage...

In this paper a new configuration of up converter is presented. In this circuit, the LO and RF (LSB) frequencies are rejected thanks to a distributed and balanced circuit. Eight GaAs PHEMTs with a gate-length of 0.25 μm are used. A conversion gain of -6 dB and a rejection over 6 dB on LO and RF (LSB) are obtained.

For more than a century there have been examples of (n3) configurations without a Hamiltonian circuit. However, all these examples were only 2-connected. It has been believed that all geometric 3-connected configurations (n3) admit Hamiltonian circuits. We present a 3-connected configuration (253) of points and lines in the Euclidean plane which has no Hamiltonian circuit.

In this paper a modified form of the most efficient resonant LLC series parallel converter configuration is proposed. The proposed system comprises of an additional LC circuit synchronized with the existing resonant tank of LLC configuration (LLC-LC configuration). With the development of power electronics devices, resonant converters have been proved to be more efficient than conventional conv...

..4bstract—A novel ultrabroad-band amplifier configuration suitable for GaAs FET’s has been developed. The developed amplifier circuit operates as a capacitor-resistor ( C–R ) coupled mnpfifier circuit in the lowfrequency range in which IS21 I for the GaAs FET’s is constant. It also operates as a lossless impedance matching circuit in the microwave frequency range in which IS21 I for the GaAs F...

A circuit configuration of a single-phase nonisolated online uninterruptible power supply (UPS) with 110-V/220-V input–output voltage ratings is proposed, allowing the bypass operation without a transformer even if the input voltage is different from the output voltage. The converter consists of an ac–dc/dc–dc three-level boost converter combined with a double half-bridge inverter. In this type...
