2.6 Dependent Sources and The Control Concept

  • Voltage-controlled current source:
  • Linear voltage-controlled current source: iout = g*vin
  • g is a constant coefficient called transconductance with unit of conductance
  • Current-controlled current source:
  • Linear current-controlled current source: (coefficient = current transfer ratio)
  • Linear voltage-controlled voltage source: (coefficient = voltage transfer ratio)
  • Linear current-controlled voltage source: vout = r*iIN (r = transresistance)
  • VCCS, CCCS, VCVS, CCVS:
