Line 187:
In FETs electrons can flow in either direction through the channel when operated in the linear mode, and the naming convention of drain terminal and source terminal is somewhat arbitrary, as the devices are typically (but not always) built symmetrically from source to drain. This makes FETs suitable for switching analog signals between paths ([[multiplexing]]). With this concept, one can construct a solid-state [[mixing board]], for example.
==Applications==
[[Audio amplifier]]
Power MOSFET's are superior than BJT's to be used in audio amplifier.Reasons for this are their negative transconductance co-efficiant and lack of second breakdown.
