  Term Definition  
     
  ACTIVE CIRCUIT AREA All areas from outside edge of the bond pads inward, except where there is an active line in the device located beyond the outside edge of the bond pads.  
       
  AIR (COUPLING) BRIDGE A raised layer of metallization used for interconnection that is isolated from the die surface by only air.  
       
  ALGORITHMS A mathematical equation that produces in a fixed number of steps the answer the answer to a question or the solution to a problem.  
       
  ALTERNATING CURRENT
- AC VOLTAGE
Either voltage or current that varies smoothly from zero to a maximum value in one direction, or polarity, and returns to zero. It then reverses its direction (polarity) and rises to a maximum value in the opposite direction, and then returns to zero to complete the cycle. This cycle is repeated continuously. The number of cycles per second is its frequency, measured in hertz (Hz). See SINE WAVE.  
       
  ANALOG AMPLIFIER (LINEAR A circuit whose output waveshape is an amplified version of its input waveshape. Also called a LINEAR AMPLIFIER.  
       
  ANALOG SIGNAL An electrical signal that has continuously varying voltages, frequencies, or phases.  
       
  ANALOG SWITCH A digitally controlled switch that provides a conductive path for a linear or analog voltage in its ON state  
       
  AMPERE The unit of measurement of electrical current flow, named after André Ampère, a 19th century French physicist. One ampere is the value of current that will be maintained in a circuit with an electromotive force of one volt and a resistance of one ohm. One ampere = 6.25 x 1018 electrons/second. See CURRENT.  
       
  AMPLIFICATION The process of increasing the voltage, current, or power of an electrical or electronic signal.  
       
  AMPLIFIER An electronic circuit that draws power from a supply voltage, or voltage source, to produce, at its output, an increased reproduction of the signal existing at its input. The amplifying component could be a transistor, vacuum tube, or an appropriate magnetic device.  
       
  ANODE One of the two terminals of a diode (positive type material) or the output terminal (also positive type material) of a silicon controlled rectifier (SCR)  
       
  ANALOG VOLTAGE A gradually changing voltage. The term is interchangeable with LINEAR VOLTAGE. For example, the voltage sensed by an automobile's speedometer is the analog of the speed of the automobile.  
       
  ÅNGSTROM UNIT A unit of length that measures wavelength and is equal to 0.1 of a billionth of a meter (1x10-10 meters). It is named after Anders Ångström, a 19th century Swedish physicist.  
       
  ARMATURE The moving part of a magnetic device consisting of one or more coils that are electrically connected to create the rotatable section of a generator. See ARMATURE in Glossary of Switches, Keyboards, and Electromechanical Relays.
