    This article presents some basic concepts for electrical circuits. A port is defined as a set of terminals that satisfies the port-Kirchhoff current law. Transfer of energy occurs when a set of terminals forms a port. For a connected RLC circuit the only port is the one that consists of all the terminals. It is explained that in order to formalize the architecture of an electrical circuit it is co... View full abstract»

    Instead of blindly tracking the rapid downsizing of supply voltage (VDD) in technology scaling, high-/mixed-voltage radio-frequency (RF) and analog CMOS circuits have emerged as a prospective alternative comes of age. An elevated VDD, or a hybrid use of I/O and core VDD's, in conjunction with thinand thick-oxide MOS transistors open up many possibilities in defining circuit topologies, while maint...

    A recent article published in this magazine has labeled fractional-order continuous-time systems as the "21st century systems". Indeed, this emerging research area is slowly gaining momentum among electrical engineers while its deeply rooted mathematical concepts also slowly migrate to various engineering disciplines. A very important aspect of research in fractional-order circuits and systems is ... View full abstract»

    Lumped constant delay lines are lowpass filters which are valued for their delay characteristics. The delay is relatively long, in some cases tremendously long. It must also be very constant over a lowpass band. This type of filter is very old, going back to the 1920's. It arises from Zobel's image parameter theory, which is generally considered obsolete in regard to any other species of filter. I... View full abstract»

    This work describes a method that computationally determines the minimum required power and sampling capacitance for a switched capacitor integrator in a sigma delta modulator, given the modulator architecture, coefficients, and desired SNDR target. The design space is quickly explored with discrete time simulations that model the finite gain, settling dynamics, and thermal noise of the integrator... View full abstract»
