“…Figure 5 shows the UGC-based realisation of a current feedback operational amplifier, as proposed by Soliman (2009) The equivalent SFG of an ideal inductor in both the impedance form and the admittance form can be represented as shown in Figure 6 (these structures were constructed on the basis of the classical inductor signal flow-graphs) (Fakhfakh, Pierzchała, & Rodansky, 2012;Fakhfakh & Pierzchała, 2013a;Mason & Zimmermann, 1960;Pierzchała & Fakhfakh, 2010). The equivalent SFGs encompass a unique capacitor and two resistors.…”

“…They were introduced in the early 60s (Carlin, 1964). Since then, it has been proven that these two 'weird' elements are very useful in analogue circuit synthesis and analysis; see, for instance, Hashemian (2008), Huang, Wang, Cheng, and Lin (2012), Pierzchała and Fakhfakh (2010), Sánchez-López, Fernández, Tlelo-Cuautle, and Tan (2011).…”

In this paper we propose a novel idea for the synthesis of active circuits. We deal with the use of unity gain cells (voltage followers, voltage inverters, current followers, current inverters) for the design of simulated grounded inductors, multifunction filters and oscillators. The starting point of the proposed idea is the operation on the signalflow graphs for such synthesis. We show that, thanks to the proposed technique, a wide number of active networks can be synthesised where all used passive components are grounded.

“…However, the equivalent inductance value L of this circuit is inversely proportional to the parameters of the OTA circuits (g m1 ,g m2 ) and this is a drawback of the circuit. In order to eliminate this drawback, an active inductor configuration using current controlled voltage sources was proposed in [2], where the value of the inductance L is proportional to the product of the parameters (r m1 r m2 ) of the controlled sources. However, this configuration is complicated because it uses additional active elements.…”

This brief presents a new structure of active inductors. These synthetic inductors are designed using current controlled voltage sources. The signal flow graph method is used for this purpose. For the practical realization, operational transresistance amplifiers (OTRAs) are replicated using current conveyors. The proposed inductors have very interesting properties because the value of its inductance is proportional to the product of the parameter of the OTRAs (r m1 r m2 ) and thus, small capacitor values can be used. Current conveyor based simulated inductors are presented and SPICE simulations are given to show the viability of the proposed synthesis technique.

“…The triple (W W γ) [52] and quartic (W W γγ) [22] gauge-boson couplings have been investigated with an effective Lagrangian after electroweak symmetry breaking. With 30 fb −1 of luminosity, the former may be determined with two to 15 times higher precision than presently available from the Tevatron, while the latter might even be improved by a factor of 10 4 over present LEP bounds with an integrated luminosity of 10 fb −1 .…”

In this review, we motivate these studies beyond the famous quote from Genesis 1, 3-4, where God said: 'Let there be light,' and there was light. God saw that the light was good, and he separated the light from the darkness. We first discuss the legacy of past photoproduction experiments at LEP and HERA and the gold-plated channels proposed for a photon collider at the ILC. We then present the emerging experimental results from RHIC and the Tevatron and three promising channels at the LHC: exclusive vector-meson production, measurements of possibly anomalous electroweak gauge-boson or top-quark couplings, and slepton production. We close with an outlook on other channels that might be interesting to study further in the future. Photon physics at lepton collidersAt circular lepton accelerators such as LEP and the electron-ring at HERA, spacelike, almost real bremsstrahlung photons are exchanged during the hard collision. At a future ILC, large particle bunch densities are needed to reach high luminosities. Then additional beamstrahlung photons will be created before the hard interaction by the coherent action of the electromagnetic field of one bunch on the opposite one. If the electron beams are collided with additional highenergy laser beams, real photons can be producedWe discuss the potential of high-energy photon collisions at the LHC for improving our understanding of QCD and studying the physics beyond the Standard Model. After reviewing briefly the legacy of past photoproduction experiments at LEP and HERA, we examine the gold-plated channels proposed for a photon collider at the ILC for their potential in a hadron collider environment. We stress that initial-state photon interactions have indeed been observed at RHIC and at the Tevatron. Three promising channels at the LHC are then presented in some detail: exclusive vector-meson production, measurements of possibly anomalous electroweak gauge-boson or top-quark couplings, and slepton production.
