Switching delay

The overall circuit delay will be a combination of the transistor switching delay (which gets smaller with smaller feature sizes), and the interconnect delay (which gets larger with smaller feature sizes). The choice of the... 

Delays are an important part of pulse sequences and may be characterized by their duration and the effect they cause. Short delays in the micro-second region such as the pre-scan delay de or power switching delays, are not normally illustrated explicitly in pulse sequences and NMR-SIM simulations do not take these types of delay into consideration because an ideal spectrometer is assumed. Such delays may seem superfluous but they should nevertheless be considered and included sometimes in the interpretation of experimental artefacts or signal distortions. These effects are discussed in detail in sections 2.2.1 and 5.8.2. 

Each link shown in Figure 5 has a capacity of 10 Mb/s in each direction and introduces a fixed 10 ps delay. E.g., such links can be considered as dedicated 10 Mb/s Ethernet trunks, the 10 ps latency accounting for the propagation delay on the wires and the switching delay introduced by an Ethernet switch. 

Figure 4.21c illustrates the results obtained using the switch model with the turn-off delay. Even if the switching delay is included into the simulation, the accuracy is not improved. 

Figure 4.21d illustrates the results obtained using the accurate model. The high-frequency oscillation as well as the switching delay is accurately reproduced. The loss of the MOSFET reduces the oscillation.
