AC Circuits with Transformers

Robust Low-Leakage Circuits

Problem: While the aggressive scaling of CMOS technology to ever smaller dimensions has enabled higher performance and integration levels, it has given rise to a plethora of new problems in the design of integrated circuits [1-4]. Reduced threshold voltages and gate oxide thicknesses have caused an alarming increase in subthreshold source-drain leakage and gate leakage power dissipation in both...

Current Conveyor Equivalent Circuits

An equivalence between a class of (current conveyor) CC II+ and CC IIcircuits is established. CC IIequivalent circuit uses one extra element. However, under certain condition, the extra element can be eliminated. As an illustration of the application of this equivalence, minimal first and second order all-pass filters are derived. In certain cases, it is possible to compensate the effect of the...

A Fast Method for Calculation of Transformers Leakage Reactance Using Energy Technique

Energy technique procedure for computing the leakage reactance in transformers is presented. This method is very efficient compared with the use of flux element and image technique and is also remarkably accurate. Examples of calculated leakage inductances and the short circuit impedance are given for illustration. For validation, the results are compared with the results obtained using practic...

DPA Leakage Models for CMOS Logic Circuits

In this paper, we propose new models for directly evaluating DPA leakage from logic information in CMOS circuits. These models are based on the transition probability for each gate, and are naturally applicable to various actual devices for simulating power analysis. We also report the effectiveness of the previously known enhanced DPA on our model. Furthermore, we demonstrate the weakness of p...
