摘要:

AbstractThis paper studies the problem of the stability of linear networks or systems depending polynomially on parameters when considering large values of the parameters. It has been taken into account that only the specification of nominal values and tolerances—and not of actual values—is physically meaningful.Algorithms to test the existence of arbitrarily large nominal values of the parameters which ensure stability either with zero tolerance, with non‐zero tolerances depending on the particular nominal values or with a non‐zero tolerance independent of the particular nominal values are proved to exist.Depending on the type of response of the above‐mentioned algorithms, analytic, polynomial and monomial functions—in a single suitable variable—that describe arbitrarily large nominal values which ensure stability in the case of zero tolerance, polynomially decreasing non‐zero tolerance and constant non‐zero tolerance respectively are proved to exist.When a monomial description with constant non‐zero tolerance is assured, algorithms which give the degrees and—in terms of rational numbers—the coefficients of the monomials and the constant non‐zero tolerance are proved to exist.Similar algorithms when only an analytic description with zero tolerance or a polynomial description with polynomially decreasing non‐zero tolera

摘要:

AbstractIn this paper we present a tight clock synchronization scheme for large‐scale multiprocessor systems. the proposed scheme consists of two symmetric loops for transmission of the master clock signals and askew cancellation circuit(SCC) for each node to be synchronized to the master clock. Each clocking signal generated by the master clock source is replicated into two identical copies and the twin signals are transmitted on two symmetric loops in opposite directions. to cancel the time skew between them caused by the transmission network, the time difference between the two clocks' arrival times at any node is first measured and stored in each node. Then each of the leading signals received from the loop in a node is issued to its functional units after the signal is delayed by half the measured phase difference. It is shown that the system clock skew can be made independent of the delay of the transmission lines by the proposed scheme at a low hardware cost.To explore the feasibility of the proposed scheme, the SCC is designed with a combination of programmable delay element arrays and a phase detector. the floor‐plan of the SCC is implemented by the MAGIC VLSI lay‐out tool based on MOSIS CMOS 2 μm technology and extensively sim

摘要:

AbstractA novel circuit configuration is presented for tunable combining multiplexers. Using reciprocal devices, the new circuit enables any channel to be tuned without the adverse effect of frequency pulling on the other channels. Experimental results in the 900 MHz band using dual‐mode dielectric resonators are in close agreement with theor
