Study Notes

Caracteristicas del transistor d'union bipolar (BJT)

  • Lo BJT es un dispositiu contrarotlat per corrent
  • Lo ganh de corrent es feble comparat als amplificadors de senhal, amb una valor de 10
  • La beta (β) es una caracteristica importanta del BJT, mesurant la relacion entre la corrent de basa e la corrent de collector

Caracteristicas del MOSFET

• Velocitat de commutacion fòrça elevada, la mai nauta entre totei lei autrei dispositius. • Comandat per tension, amb una poténcia de comandament febla. • Requiments de circuit de comandament simplificat, sens saturation prigonda e zeros volts per l'estat de desligament. • Coeficient termic negatiu, que mena a una division de corrent egal entre lei dispositius connectats en paralèl. • Pèrdas de conduccion mai elevadas que lei BJT. • Disponible amb ratings de poténcia febla a mejana (centenas d'amperes e 100s de volts).
