Circuit

Circuit may refer to:

Science and technology

Electrical engineering

• Electrical circuit, a complete electrical network with a closed loop giving a return path for current
  • Analog circuit and digital circuit, which use continuous and discrete signal levels, respectively
  • Electronic circuit, containing "active" (nonlinear) electronic components capable of performing amplification, computation, and data transfer

    • Integrated circuit, a set of electronic circuits on a small "chip" of semiconductor material
      • Mixed-signal integrated circuit, containing both analog and digital signals
  • Balanced circuit, in which paths are impedance-matched
  • Printed circuit board, on which electronic components are supported and connected using copper tracks on a non-conductive substrate
  • Series and parallel circuits, two ways in which electrical components may be interconnected
  • Simple filters, including:
    • LC circuit or tank circuit, consisting of an inductance and a capacitance
    • RC circuit, consisting of a resistance and a capacitance
