Before revision: BJTs and FETs Mixed Although still in relatively common use, there is limited relevance of these device-specific power-supply designations in circuits that use a mixture of bipolar and FET elements, or in those that employ either both NPN and PNP transistors or both n- and p-channel FETs.
