Encompasses types of circuits such as analog, digital and linear circuits


  • Analog circuits - electric communication links using an continuous signal which represents some other quantity
  • Bipolar transistor circuits - a three-terminal electric device (using both electrons and holes), often used in amplification or switching
  • Digital circuits - circuits that represent signals using discrete bands in an analog levels, instead of continuous range
  • Linear circuits - an electronic circuit where an input frequency matches the output frequency
  • MOSFET circuits - a metal-oxide-semiconductor field-effect transistor circuit, a circuit which uses such a transistor for amplifying or switching electronic signals
  • Magnetic circuits - a circuit made up of one or more closed loop paths containing a magnetic flux
  • Nonlinear circuits - a circuit in which a certain frequency input is not necessarily matched by the same frequency output
  • Passive circuits - circuits that consume but do not produce or increase energy
  • Programmable circuits - circuits whose function is initially undefined and can be reconfigured
  • Pulse circuits - circuits that are used for high-powered signals with rapid pulses of energy
  • Sequential circuits - a circuit in which the output does not only depend on present input but on the history of the input
  • Solid-state circuits - circuits built entirely from solid materials, in which the electrons are confined entirely within the solid material
  • Summing circuits - a circuit which adds several inputs together
  • Switching circuits - circuits that establish a dedicated communications channel between two nodes
  • Thyristor circuits - circuits with four layers of alternating P and N type material, which function as bistable switches
  • Track circuits - an electrical device used to detect the presence or absence of a train on the train tracks
