A 6W uneven doherty power amplifier in GaN technology
No full textIn this paper the design of a 6W uneven GaN Doherty power amplifier is presented. The Doherty PA is designed to achieve high efficiency for modulated signals with high peak to average power ratio used in modern wireless communication systems. The Doherty amplifier has been designed using two equal sized GaN devices for the Main Class AB and Peaking Class C amplifiers. An uneven power divider is used at the input to deliver more input power to the Peaking amplifier than the Main amplifier. The measured maximum output power of the realised uneven Doherty is 38 dBm with 60% of peak power added efficiency (76% of drain efficiency). The power added (drain) efficiency is higher than 52% (62%) up to 6 dB of back off, or 42% (45%) up to 10 dB of back off
Gnesioi filoi: the Search for George Syncellus’ and Theophanes the Confessor’s Own Words, and the Authorship of Their Oeuvre
No full textIn a nutshell: 1. I believe that Ekloge Chronographias of George Syncellus and Chronographia
of Theophanes the Confessor should be treated as a single project, undertaken in turn by
two authors; 2. There are important stylistic differences between the two parts, noticeable in the
fragments, in which the authors deliver some editorial remarks or disclose their personal opinions;
from a wider selection of such phrases, references to the past or future such as ‘as I have mentioned
/ as I said / as have been said / as we demonstrated above, etc.’, being diverse and individual, are
especially helpful. 3. This observation is of great use not only for the texts analysed here, it may be
used to confirm authorship of many other texts. 4. As for George and Theophanes, the TLG search
of such structures in all extant classical Greek and Byzantine output confirms the statement nr 1,
with clauses like ὡς προέφην
/ καθὼς καὶ προέφην
/ ὡς προέφημεν / καθὼς προέφημεν both rare
in the whole preserved corpus, and relatively often used by the author of Chronographia. The style
of the proemium of Chronographia fits the rest of the work and differs from Ekloge Chronographias. 5.
Precise analysis of a wider group of similar clauses shows that Ekloge Chronographias and Chronographia
were written by two different authors; Chronographia was created by one author, distinctive and
independent, no matter how reproductive at the same time he was. I see no convincing arguments
not to call this author Theophanes. Some later and partial editiorial interventions to Chronographia,
conceivable (rubrics?) and in some instances even certain, do not challenge this view. 6. Only a few
entries from the initial parts of Chronographia fit more the George’s work; their style and content
bear much more similarities with Ekloge (in AM 5796, 5814, 5818, 5827, 5828). These paragraphs,George’s aphormai, probably in form of loose notes, were inserted to Chronographia by its author
the same way as he used his sources for the subsequent parts; they did not reach beyond the times
of Constantine I. 7. I do not dismiss the message of the proemium to the Chronographia as it is much
more credible than the discussion, sometimes hypercritical, on the vitae and the scraps of the Confessor’s
biography. I see no reason not to believe that the idea established and developed by George
was then taken over by his friend; the differences result from the independent work of the former
and then of the latter, presumably with only rudimentary guidance at the beginning. 8. The ‘genuine
friendship’, the crucial relation between the two authors is still the most useful key to understand the
history of the tripartita – therefore, I analyse it in the final part of the paper
La littérature à Constantinople du XII ème siecle: le changement des directions?
No full textThe author sketches the intellectuallandscape of twelfth-century Constantinople
with the special reference to the trends in literature and variety of its
genres.
The period, dominated by the Komnenos dynasty, with an increasing economic
prosperity and all its cultural and social consequences, generated a demand
for trained bureaucrats in secular and ecclesiastical spheres and, as far as
writers and literary practitioners are concerned, provided new possibilities of
imperial and aristocratic families' patronage. By the 1120s and 1130s a more
regular provision of higher education was in existence in Constantinople to such
an extent that supply had outstripped demand. It bore a great significance as the
extent to which writers depended on the patronage as their sole means of support
was a new feature of the era. John Tzetzes' career is quoted as an example of this
process and his literary output, covering much that would be classed now not as
a literature but e.g. scholarship, leads to a problem of an understanding of
a literature itself.
The characteristic features of byzantine literature of the period are named,
f.ex. the linguistic usages in fine writing, that followed those of the ancient
grammarians and dictionaries and only on very rare occasions using the vernacular
language that was in current use. The Byzantine literary production of
the time, understood widely, conforms on the whole to the pattern, in which
a deeply Christianized society focuses its most attention on composing and preserving
material produced as aids to correct Christian thought and worship. In
a consequence, secular material formed a very small proportion of the total
writerly output and the existing literary forms aspired to conveyed material abhorent
to many of the literary practitioners.
There are, on the other hand, three particularly important divergences from
what could be perceived as the standard Byzantine pattern. Writing in vernacular,
colloquial Greek appears quite suddenly, usually in snippets, breaking the
linguistic self-censorship that had been in place for centuries. Erotic fiction, created
by Theodore Prodromos, Constantine Manasses. Niketas Eugenianos. Eumathios
Makrembolites and the anonymous author of Digenis Akritis, reappeared
in the form of novels created under the profound influence of the late antique
authors. The third aspect is the copious production of verse for special occasions,
a long Byzantine habit, deriving from the epideictic oratory of the Second Sophistic,
and in the twelfth century widespread in the imperial and aristocratic households.
The last part of the lecture focuses on Manganeios Prodromos, an author
whose poetry of this genre survived, as well as on his social and literary connections
(including a role of sevastokratorissa Eirene and lakovos Monachos)
