VLSI designA typical processor central processing unit devotes a considerable amount of processing time inperforming arithmetic operations, particularly multiplication operations. Multiplication is one of thebasic arithmetic operations and it requires substantially more hardware resources and processing timethan ...
Effective capacitance in this sense implies the capacitance presented at the input. Check out the inverter shown in the figure below, where PMOS is twice the unit size of NMOS to give equal rise/fall time. Figure 1. Unit inverter circuit. All images adapted from CMOS VLSI Design (4th ed....

11.Introduced in this paper is a new approach for VLSI interconnect global routing that can optimize both congestion and delay, due to routing topology flexibilities.文章介绍了一个可以同时考虑时延约束和拥塞度优化的VLSI总体布线新方法。 12." Thermal time delay switch, Generic specification of"GB/T14...
The final issue to be considered in this application is the pipelineability of the transformer structure. We have already seen that the linear complexity and good finite precision properties of the structure make it a good candidate for VLSI implementation, however, as explained in Section. II C...
The study of asynchronous circuit behaviors in the presence of component and wire delays has received a great deal of attention. In this paper, we consider
To test the memory cores, in this paper we propose a generalized embedded test pattern generat... WL Wang,KJ Lee,JF Wang - International Symposium on Vlsi Technology 被引量: 5发表: 1999年 Embedded test pattern generator for memories With the modern day electronic gadgets the demand for ...
A delay switch comprising a delay element provided in the center of a body to produce a delayed output, a delay cam unit provided on one side of the delay element to start its actuation always from an identical position in response to the delayed output, and switching contact members electric...
VLSI Circuit Technologies 2.3.3 Propagation Delay in CMOS Circuits The propagation delay, τp, in a digital circuit is defined: (2.3)τp=τout−τin where τout and τin are the time instances when the output and input voltage cross the VDD/2 level, respectively [2, 7, 23–25], Sp...
