“…As the buffers are typically designed using complementary metal-oxide-semiconductor (CMOS) technology, the input gate of every MOS along the customised rows and columns serves as the knob to tune the delay value, which is not convenient and the architecture is unnecessarily crowded. 1) and (2) directly impact the propagation delay (τ = R ON × C G' ) of the delay circuit [18,19].…”

In the design of modern processor chips, proper clock distribution is a very important aspect which impacts the chip performance. It is the active cell of delay circuits and cells with variable delay that have the major involvement in clock distribution, thereby deciding the time slacks of all functionalities inside the chip. Because they help in proper input to output signal transmission with the adjustment of variable timing delays and monitor the output signal to have equal rise/fall time, which most of the existing delay elements fail to deliver. Therefore in this article, we have proposed an input vector based design of variable delay with balanced rise time and fall time for the output signal. We have also estimated the delay and output voltage in terms of a mathematical model. This new configuration is executed across the commercial platform of Cadence Virtuoso® using 90nm technology node while steered by a 1GHz input signal and power supply of 1.1 V. The execution outcome confirms the desired features of our proposed design under typical conditions and even in process corner variations.

A New Method to Optimize the Satisfaction Level of the Decision Maker in Fuzzy Geometric Programming Problems

Geometric programming problems are well-known in mathematical modeling. They are broadly used in diverse practical fields that are contemplated through an appropriate methodology. In this paper, a multi-parametric vector α is proposed for approaching the highest decision maker satisfaction. Hitherto, the simple parameter α , which has a scalar role, has been considered in the problem. The parameter α is a vector whose range is within the region of the satisfaction area. Conventionally, it is assumed that the decision maker is sure about the parameters, but, in reality, it is mostly hesitant about them, so the parameters are presented in fuzzy numbers. In this method, the decision maker can attain different satisfaction levels in each constraint, and even full satisfaction can be reached in some constraints. The goal is to find the highest satisfaction degree to maintain an optimal solution. Moreover, the objective function is turned into a constraint, i.e., one more dimension is added to n-dimensional multi-parametric α . Thus, the fuzzy geometric programming problem under this multi-parametric vector α ∈ ( 0 , 1 ] n + 1 gives a maximum satisfaction level to the decision maker. A numerical example is presented to illustrate the proposed method and the superiority of this multi-parametric α over the simple one.
