Left: A few layers of epithelium are noted, lacking a palisading of the nuclei and showing an abrupt junction
with the surrounding fibrous tissue.
In order to maintain the ESD clamping performance, it is crucial to have silicon processes in place to isolate the pin diodes from the zener area, with an abrupt junction, while leaving enough silicon real estate to maintain the larger zener junction required to achieve good ESD clamping voltage performance and high ESD robustness.
This isolation needs to create an abrupt junction in a very small space in order to maintain a large enough zener junction dimension required to achieve the low ESD clamping voltage seen by the ESD9L5.0ST5G.
Seen from the St Martin's side, its sinuous curves and metallic cladding strike visual sparks off the refurbished church ("Spettacolare!" I overheard one camera-wielding Italian tourist exclaim) but on the south side its looming mass does not encourage pedestrians to linger and seen from the Moor Street side its abrupt junction
with the rest of the Bullring development, like a sliced Swiss roll, raises the question whether it is really a building at all.
With an abrupt junction, the transfer is carried out suddenly.
Basically, the quality of abrupt junction crossings is significantly better than that of hyperabrupt crossings.
MMICAD then can plot a typical abrupt junction
varactor diode C-V curve, which can then be used in an actual oscillator circuit to see the degree of nonlinearity that it produces.
Additionally, the analysis of a frequency doubler is the most straightforward and closed form solutions are often possible, that is those for the abrupt junction diode.
A simple and approximate model for the abrupt junction varactor diode is shown in Figure 3.
A detailed analysis for abrupt junction multipliers, including frequency doublers, has been performed  to establish performance limits and operating impedance levels in terms of basic device parameters.
An abrupt junction varactor diode that has parameters suitable for delivering 0.25 W of output power in a 22 to 44 GHz frequency doubler circuit is identified in Table 1.
For an abrupt junction
varactor, the junction capacitance [C.sub.j] is related to the applied bias voltage V by (12) [Mathematical Expression Omitted] Where [C.sup.1] is the junction capacitance with zero bias voltage.
