“…There are plentiful reports associated with the physical properties of miniaturized two-loop (or two-dimensional) circuits [8-12] and more high multi-loop circuits [13-16] including their diverse variants. Various applications which use two-loop circuits include a switch-level resistor-capacitor (RC) model of an n-transistor (see Figure 3 of [8]), a design of a prototype of current-mode leapfrog ladder filters (Sect.…”

The time behavior of DSN (displaced squeezed number state) for a two-dimensional electronic circuit composed of nanoscale elements is investigated using unitary transformation approach. The original Hamiltonian of the system is somewhat complicated. However, through unitary transformation, the Hamiltonian became very simple enough that we can easily treat it. By executing inverse transformation for the wave function obtained in the transformed system, we derived the exact wave function associated to the DSN in the original system. The time evolution of the DSN is described in detail, and its corresponding probability density is illustrated. We confirmed that the probability density oscillates with time like that of a classical state. There are two factors that drive the probability density to oscillate: One is the initial amplitude of complementary functions, and the other is the external power source. The oscillation associated with the initial amplitude gradually disappears with time due to the dissipation raised by resistances of the system. These analyses exactly coincide with those obtained from classical state. The characteristics of quantum fluctuations and uncertainty relations for charges and currents are also addressed.

“…The step time responses of SP-GNRFETs, like those of pitched CNTFETs [21] and unlike those of GNR/CNT-based local interconnects [22,27], exhibit multi-harmonic oscillations. This different behavior can be explainedby a comparison of the corresponding circuit models and transfer functions.…”

“…(2)). On the other hand, for interconnects made of either MLGNR [21] or the multiwall CNT (MWCNT) bundle [27], the signal passes through a single path, and hence the numerator of the corresponding transfer function is unity. Amplification of each harmonic in the output of SP-GNRFETs and pitched CNTFETs can damagethe input to the next stage on the chip in RFICs.…”

“…On the other hand, a chip interconnects are used in both open and closed loop systems. Hence, any change in stability and bandwidth of an open loop system such as interconnects leads to change in stability and bandwidth of closed-loop systems on the chip[33]. In this paper, we present a matrix formulations for equivalent circuit model of coupled MLGNR interconnects, based (a) Geometry of double coupled MLGNR interconnects on a ground plane and (b) its TLM circuit model.…”
