No late Projects
will be accepted after Thursday, May 9 at 5 PM!
Your BJT design should
meet the performance specifications to within 10% at both 300K and 360K.
(Essentially, this
means that bdc>
45, fT > 18 GHz, VA > 9 V and Vpunchthrough
> 9 V.)
If your BJT design
does NOT meet the performance specifications to within 10% at both 300K
and 360K, then 10 points will be deducted from your project score.
If your BJT design
meets the performance specifications to within 5% at both 300K and 360K,
then you will receive 10 points extra credit on your project score.
Note: The depletion
width associated with the collector/sub-collector n/n+ junction is actually
located on the sub-collector side of this junction. Hence, there
is no need to account for this depletion width in calculating the quasi-neutral
collector width. We will not deduct any points if you did so, however.
Your BJT design does
not
need to meet the specifications when the metallurgical base width
(WB) and base doping (NB) are varied by +/- 10%.
You should simply show how the BJT performance parameters change with these
variations, and explain them.
For the IC
vs. VCE plot, VCE should range from 0 V to 10 V.
