I am new to SiGe HBT layout.
I am using a CBEBC transistor layout - that is, two collectors and two bases.
I attached a picture.
My question is: how do I lay this out - do I connect the bases and collectors in a kind of "fishbone" connection ? I attached what I assume to be a correct way to do the lay out of the individual transistor. Is what I attached a correct method for CBEBC layout ?
Does anyone have any books, papers, thesis or could someone provide a screen capture/screen shot of how to connect/layout the individual transistor with the CBEBC structure to see if I am on track ?
Thank you.
