Power is a major constraint in Digital VLSI circuits, due to reduction in sizes of Metal Oxide Semiconductor (MOS) transistors are scaling down. Low-power technologies are used to diminish the power utilization be able to be classified as Sub-threshold CMOS and Adiabatic logic tachniques. In, Sub-threshold CMOS defines a system which reduces the power utilization to inferior than the threshold voltage of a MOS Device, where as Adiabatic logic circuit is a method which minimizes the energy usage through suppress the applied voltage to the resistance of a given VLSI design. This effort deals to offer a subthreshold adiabatic logic circuit of low power CMOS circuits that uses 2φ clocking subthreshold Adiabatic Logic. The digital circuits were designed in HSPICE using 0.18 μm CMOS standard process technology. It is evident from the results that the 2φ Clocking Subthreshold Adiabatic design is beneficial in major application where power starving is of major significance at the same time as in elevated its performance efficiency in DSP processor IC, System on chip, Network on chip and High speed digital ICs.


There is enormous demand for high speed VLSI networks in present days. The coupling capacitance and interconnect delay play a major role in judging the behavior of on chip interconnects. There is an on chip inductance effect as we switch to low technology that leads to delay in interconnecting. In this paper we are attempting to apply second order transfer function designed with finite difference equation and transform Laplace at the ends of the source and load termination. Analysis shows that the current signaling mode in VLSI interconnects provide better time delay than the voltage mode

AbstractUltracompact and low-power-consumption optical switches are desired for high-performance telecommunication networks and data centers. Here, we demonstrate an on-chip power-efficient 2 × 2 thermo-optic switch unit by using a suspended photonic crystal nanobeam structure. A submilliwatt switching power of 0.15 mW is obtained with a tuning efficiency of 7.71 nm/mW in a compact footprint of 60 μm × 16 μm. The bandwidth of the switch is properly designed for a four-level pulse amplitude modulation signal with a 124 Gb/s raw data rate. To the best of our knowledge, the proposed switch is the most power-efficient resonator-based thermo-optic switch unit with the highest tuning efficiency and data ever reported.

AbstractPlasmons, as emerging optical diffraction-unlimited information carriers, promise the high-capacity, high-speed, and integrated photonic chips. The on-chip precise manipulations of plasmon in an arbitrary platform, whether two-dimensional (2D) or one-dimensional (1D), appears demanding but non-trivial. Here, we proposed a meta-wall, consisting of specifically designed meta-atoms, that allows the high-efficiency transformation of propagating plasmon polaritons from 2D platforms to 1D plasmonic waveguides, forming the trans-dimensional plasmonic routers. The mechanism to compensate the momentum transformation in the router can be traced via a local dynamic phase gradient of the meta-atom and reciprocal lattice vector. To demonstrate such a scheme, a directional router based on phase-gradient meta-wall is designed to couple 2D SPP to a 1D plasmonic waveguide, while a unidirectional router based on grating metawall is designed to route 2D SPP to the arbitrarily desired direction along the 1D plasmonic waveguide by changing the incident angle of 2D SPP. The on-chip routers of trans-dimensional SPP demonstrated here provide a flexible tool to manipulate propagation of surface plasmon polaritons (SPPs) and may pave the way for designing integrated plasmonic network and devices.
