The Switched-Resistor (S-R) approach is gaining popularity among integrated circuits designers because it allows to implement very high equivalent resistances, and thus large time constants, in CMOS circuits. In this paper, we present an in-depth analysis of the S-R technique propose a novel detailed model which accurately predict value resistance even for values duty cycle as low 0.0001% resul...

The voltage margin of a resistor-logic demultiplexer can be improved significantly by basing its connection pattern on a constant-weight code. Each distinct code determines a unique demultiplexer, and therefore a large family of circuits is defined. We consider using these demultiplexers for building nanoscale crossbar memories, and determine the voltage margin of the memory system based on a p...

Let G be a connected noncompact simple Hermitian symmetric group with nite center. Let H() denote the geometric realization of an irreducible unitary highest weight representation with highest weight. Then H() consists of vector-valued holomorphic functions on G=K and the action of G on H() is given in terms of a factor of automorphy. For highest weights corresponding to ladder representations,...

We present a scaling theory for charge transport in disordered molecular semiconductors that extends percolation theory by including bonds with conductances close to the percolating one in the random-resistor network representing charge hopping. A general and compact expression is given for the charge mobility for Miller-Abrahams and Marcus hopping on different lattices with Gaussian energy dis...

It is shown that, unlike the case of the distribution of currents in a random resistor network, all negative moments of the harmonic measure in diffusion-limited aggregates exhibit power-law scaling with sample size.

Two chaos generator circuits using dual-output second-generation current conveyors [DO-CCIIs] as active devices with grounded passive components are realized. The starting circuit is a voltage-mode four-phase sinusoidal quadrature oscillator [VMFPSQO] circuit for realizing both the chaos generators. The first chaos generator is derived by modifying the VMPFSQO by inserting an additional frequen...

igh performance microprocessors require a lowvoltage, high-current power supply with fast transient response. Therefore, interleaved multiphase synchronous buck converters have gained popularity as the VRM for these microprocessors. Multiphase converters must share load current to balance thermal stress on each phase, so it’s important to address current sensing and sharing. You can use the cur...

Abstract In this paper, new circuit techniques are proposed and applied for low-power, high-resolution capacitance sensing. The first is a CMOS inverter-based resistor-capacitor oscillator that consists of resistor, capacitor, three inverters, allowing it to operate at low supply voltage power with wide sensing range. second voltage-integration feedback (VIF), which suppresses low-frequency jit...

We introduce seven new versions of the Kirchhoff-Law-Johnson-(like)-Noise (KLJN) classical physical secure key exchange scheme. While these practical improvements offer progressively enhanced security and/or speed for the non-ideal conditions, the fundamental physical laws providing the security remain the same. In the "intelligent" KLJN (iKLJN) scheme, Alice and Bob utilize the fact that they ...
