im currently having to do a project with 0 university assistance thanks to covid.
the aim is to design a two stage bipolar transistor and calculate the components required for the specifications.
i have calculated several values. heres the schematic.
with and input of 15 v and VE1 having to be
i chose a VE1 value of 3v
the transistor used is the BC846B
the supply voltage is 15 v
the collector currents 1 (ICq1) = 1.5mA
the collector current 2 (ICq2) = 7.5 mA
output voltage swing= max
frequency response = 50 20 khz
i must calculate the required specifications for each component
i have so far calculated
VE1= 3v
VE2= 8.4v
RE1 at 2k ohms VE1/ICQ1
RC1 at 4k ohms VRC1/ICQ1
RE2 = 1120k ohms VE2/ICQ2
however im unsure on how to calculate the other areas. this is all ive been given with no lectures or contact since early april.
any assistance or formula's would be greatly appreciated im not asking for answers just help with actually understanding what the equations mean and how i can calculate whats required.
