Target entity: Widlar bandgap reference (attributed)
Context triple: [Bob Widlar, hasConceptNamedAfter, Widlar bandgap reference (attributed)]
  • A. LM-series analog ICs
    LM-series analog ICs are a widely used family of linear integrated circuits, including voltage regulators, operational amplifiers, and timers, originally introduced by National Semiconductor for general-purpose analog signal processing and power management.
  • B. NE555 timer
    The NE555 timer is a widely used integrated circuit that provides precise timing, pulse generation, and oscillator functions in countless electronic circuits.
  • C. Lilienfeld field-effect transistor concept
    The Lilienfeld field-effect transistor concept is an early theoretical design for a voltage-controlled semiconductor device that anticipated the modern field-effect transistor decades before it became practical.
  • D. Esaki diode
    The Esaki diode is a heavily doped semiconductor tunnel diode that exhibits negative differential resistance, enabling high-speed and microwave-frequency electronic applications.
  • E. µA741
    µA741 is a classic general-purpose operational amplifier integrated circuit widely used in analog electronics for signal conditioning, filtering, and amplification.
  • F. None of above. chosen
