For circuit designs that use complementarybipolar transistors,you sometimes need to sort the NPNand PNP transistors to have matchingdc-current gains (β). One example of acircuit requiring matching is ...

This article presents the basic analysis and design equations of a 2-transistor configuration using both polarities of transistors: the “complementary” two-BJT configuration. Transistor combinations ...

Offered as enhanced versions of the FMMT491 and 591, the CMPT491E (npn) and CMPT591E (pnp) complementary transistor pair retain all the features and specifications as their predecessors. The exception ...

Dubbed BiCOM-III, TI's recently announced silicon-germanium (SiGe) complementary bipolar-CMOS manufacturing process integrates both NPN- and PNP-type bi-polar transistors. The result of this ...
