Due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. Although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...

Circuits composed of threshold gates (McCulloch-Pitts neurons, or perceptrons) are simplified models of neural circuits with the advantage that they are theoretically more tractable than their biological counterparts. However, when such threshold circuits are designed to perform a specific computational task, they usually differ in one important respect from computations in the brain: they requ...

Constant-depth polynomial-size threshold circuits are usually classi ed according to their total depth. For example, the best known threshold circuits for iterated multiplication and division have depth four and three, respectively. In this paper, the complexity of threshold circuits is investigated from a di erent point of view: explicit AND, OR gates are allowed in the circuits, and a thresho...

Leakage power reduction is extremely important in the design of scaled CMOS logic circuits. The dominant leakage components of such circuits are the sub threshold leakage and the thin-oxide gate leakage. This paper describes an efficient leakage reduction method that considers both these components, and is based on the selective insertion of control points. The selection is based on the leakage...

In this paper we investigate the computational power of threshold{ AND circuits versus threshold{XOR circuits. Starting from the observation that small weight threshold{AND circuits can be simulated by small weight threshold{XOR circuits we pose the question whether a Supported by the grant A1019602 of the Academy of Sciences of the Czech Republic. A major part of the results were obtained whil...

Noise in digital logic circuits does not reduce with the scaling down of CMOS devices. The conventional CMOS design does not provide noise immunity when the circuits are operated in the sub threshold region. In order to enhance the performance of the circuit and to handle the errors caused due to noise that are random and dynamic in nature, a cost effective probabilistic based noise tolerant ci...

Subthreshold VLSI circuits design received ample interest due to rapid growth of portable devices. The portable domain places in flexible limitation on the power dissipation. Though, device operating in subthreshold region shows huge potential towards satisfying the ultra low power requirement, it holds lots of difficult design issues. As integration density of interconnects increases at every ...
