Quantum information processing holds great promise for communicating and computing data efficiently. However, scaling current photonic implementation approaches to larger system size remains an outstanding challenge for realizing disruptive quantum technology. Two main ingredients of quantum information processors are quantum interference and single-photon detectors. Here we develop a hybrid su...

This paper presents a new structure for a six-port reflectometer which due to its simplicity can be implemented very easily in monolithic microwave integrated-circuit (MMIC) technology. It uses nonmatched diode detectors with a high input impedance which are placed around a phase shifter in conjunction with a power divider for the reference detector. The circuit has been fabricated using the F2...

A new automatic tuning circuit based on synchronous rectification scheme is proposed and functions in the idle periods between the burst-mode transmissions. The proposed CMOS tuning circuit can be fully integrated with the front-end filter. Simulation results employing 0.5μm CMOS technology have verified that the center frequency is automatically tuned to 1.25GHz with 10% process variation pres...

There have been great advances in integrated circuits technology in recent years which have both made feasible and generated major interest in electronic circuits which employ more than two levels of signals. These circuits, called multiple valued logic circuits, offer several potential oppourtinities for the improvement of VLSI circuit designs. In this paper we review developments and potentia...

The very fast growing market of portable equipment is increasing interest in low power integrates circuit. So, designing low power integrated circuits requires reduction of supply voltages and interconnection parasitic to minimum but reduction in supply voltage implies series of problems in circuit design. To overcome these issues, an Ultra low power low voltage two stage class AB CMOS fully di...

A 5Gb/s optical receiver front-end for optical interconnection is presented in this paper. A transimpedance amplifier (TIA), limiting amplifiers (LA), output buffer and a bias circuit are integrated in deep Nwell 0.18 m CMOS technology. As the input current amplitude is 30 A, the differential output voltage is achieved to be 124 mV. The linear gain is 78.8dB and consumes 200mW under 1.8V supply...

The enhancement-mode MOSFET is the primary active device used in present-day digital and mixed-signal integrated circuit processes. Thus, it is important to introduce this device and associated circuit design methods early in the electronics curriculum. This article discusses four integrated circuit MOSFET amplifier configurations; the current source/active load stage, the source follower, the ...
