This Letter presents a novel and extremely compact circuit topology able to implement a generalized threshold logic function with two thresholds. The circuit consists of resonant tunnelling diodes (RTDs) and heterostructure field effect transistors (HFETs). Introduction: Resonant tunneling devices are nowadays considered the most mature type of quantum-effect devices. They are already operating...

A nonlinear resonant circuit comprising a SQUID magnetometer and a shunting capacitor is studied as a readout scheme for a persistent-current qubit. The flux state of the qubit is detected as a change in the Josephson inductance of the SQUID magnetometer, which in turn mediates a shift in the resonant frequency of the readout circuit. The nonlinearity and resulting hysteresis in the resonant be...

A new methodology for developing average models of resonant converters is presented and verified against cycle by cycle simulation. The proposed model ing approach applies the concept of Rac(t) which represent the instantaneous effective load of the resonant network. Unlike the treatment given in previous studies, the value of Rac is evaluated here dynamically as a function of the temporal low-...

High Tc superconductor (HTS) technology has been used to develop an advanced high Q resonant circuit and its devices. With a HTS, a very high Q circuit can be achieved; consequently special aspects such as high voltage generation and high current control can be theoretically and practically realized. Theoretical study has been carried out, as well as a practical approach has been made for the c...

This paper proposes a new resonant gate driver circuit for a soft switching synchronous buck converter in a fixed load condition. The switching energy can be fully recovered during current commutation phase in the gate driver while the diode conduction losses in the low and high side switches can be substantially reduced by employing additional L and C resonant in the circuit. Using PSpice simu...

This work is about the analysis of dead time variation on switching losses in a Zero Voltage Switching (ZVS) synchronous buck converter (SBC) circuit. In high frequency converter circuits, switching losses are commonly linked with high and low side switches of SBC circuit. They are activated externally by the gate driver circuit. The duty ratio, dead time and resonant inductor are the parameter...
