MOSFET Basics

Structure

  • Source (S)
  • Drain (D)
  • Gate (G)
  • Types

    N-Channel

  • Conducts when VGS > Vth
  • Carriers are electrons
  • Low on-resistance
  • P-Channel

  • Conducts when VGS < Vth
  • Carriers are holes
  • Higher on-resistance
  • Main Parameters

    ParameterDescription
