6.5.5 Characterization Results for a 4ns delay element Figure 6-32 shows the input and the delayed waveforms for a 4ns delay element. Figure 6-33 shows the Q and Q~ nodes of the internal CMOS thyristor. Appendix D shows the characterization data collected for the 4ns delay element with different drive strengths.
