A Distortion Contribution Analysis (DCA) obtains the distortion at the output of an analog electronic circuit as a sum of distortion contributions of its sub-circuits. Similar to a noise analysis, a DCA helps a designer to pinpoint the actual source of the distortion. Classically, the DCA uses the Volterra theory to model the circuit and its sub-circuits. This DCA has been proven useful for sma...

The paper deals with the immunity to Electromagnetic Interference (EMI) of current source for Ultra-Low-Voltage Integrated Circuits (ICs). Based on properties IC building blocks, such as current-splitter and correlator, a novel generator is conceived. proposed solution suitable provide currents ICs operating in sub-threshold region even presence an electromagnetic polluted environment. EMI comp...

Sub-circuit recognition (SR) is a problem of recognizing sub-circuits within a given circuit and is a fundamental component in simulation, verification and testing of computeraided design. The SR problem can be formulated as subgraph isomorphism problem. Performance of previous works is not scalable as the complexities of modern designs increase. In this paper we propose a novel Prüfer-encoding...

For ordinary circuits with a xed upper bound on the maximal fanin of gates it has been shown that logarithmic redundancy is necessary and suucient to overcome random hardware faults. Here, we consider the same question for unbounded fanin circuits that in the noiseless case can compute Boolean functions in sublogarithmic depth. In this case the details of the fault model become more important. ...

In Very Large Scale Integration (VLSI), interconnect design has become a supreme issue in high speed ICs. With the decreased feature size of CMOS circuits, on-chip interconnect now dominates both circuit delay and power consumption. An eminent technique known as repeater/buffer insertion is used in long interconnections to reduce delay in VLSI circuits. This paper deals with some distinct low p...

Magnetoelectronic devices, which combine ferromagnetic materials with conventional silicon structures, o er the potential to add non-volatile storage to electronic systems, eliminating their vulnerability to data loss due to power supply interruptions. We present a set of circuits, based on the Hybrid Hall E ect device, that combine logic with non-volatile storage. These circuits can be con gur...

One of the prominent current challenges in complexity theory is the attempt to prove lower bounds for T C, the class of constant-depth, polynomial-size circuits with majority gates. Relying on the results of Williams (2013), an appealing approach to prove such lower bounds is to construct a non-trivial derandomization algorithm for T C. In this work we take a first step towards the latter goal,...

Rearranging of the logic equations which define the carry lookahead principle and using floating gate circuits allow us to obtain adders with a better performance than the traditional ones. The functions defining functionality of the adder are expressed as threshold functions which have been implemented by resorting to νMOS circuits. A 64 bit adder has been implemented using this approach in a ...

In the paper we show that there is a close relationship between the energy complexity and the depth of threshold circuits computing any Boolean function although they have completely different physical meanings. Suppose that a Boolean function f can be computed by a threshold circuit C of energy complexity e and hence at most e threshold gates in C output “1” for any input to C. We then prove t...
