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....
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...
A performance-evaluation simulator, such as a cycle-accurate simulator, is a key tool for exploring appropriate asynchronous Network-on-Chip (NoC) architectures in early stages of VLSI design, but its accuracy is insufficient in practical VLSI implementation. In this paper, a highly accurate ...
Timing characteristics of a standard cell flip-flop in a 130 nm CMOS technology. View chapter Book 2015, Top-Down Digital VLSI Design Chapter Static Circuits SOLUTION δlogic must be at least 0 + 1 – 0.5 – 2 = −1.5 FO4 delays. Because logic delays are always nonnegative, it is ...
higher current levels in transistors lead to more power consumption per unit. The higher VDDL will reduce the latency of propagation. A higher VDDL can result in a lower energy use per operation because of quicker switching, even though overall energy consumption might increase. To achieve the ...
A delay locked loop (DLL) apparatus includes a first delay unit converting a reference clock into a rising clock. A second delay unit converts the reference clock into a falling clo
If the structures of the NAND gates (1, 2) are the same, the unit delay times (蟿) can be made to agree with each other with high accuracy.doi:WO2004086622 A1Yamawaki, Masashi c/o FUJITSU VLSI LIMITEDWO
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...
