Target entity: Widlar current source Context triple: [Bob Widlar, hasConceptNamedAfter, Widlar current source]
-
A.
Widlar current source
chosen
The Widlar current source is an analog integrated circuit design that produces a precise, low-magnitude reference current using a resistor and transistor pair with emitter degeneration, widely used in early linear ICs.
-
B.
Widlar bandgap reference (attributed)
The Widlar bandgap reference is an early, influential voltage reference circuit design that produces a temperature-stable output voltage by exploiting the bandgap energy of silicon, attributed to analog IC pioneer Bob Widlar.
-
C.
LM10 operational amplifier
The LM10 operational amplifier is a pioneering low-voltage, low-power analog integrated circuit designed by Bob Widlar, widely used for precision applications in compact and battery-powered systems.
-
D.
µA702 operational amplifier
The µA702 operational amplifier is one of the earliest monolithic integrated op-amps, designed by Bob Widlar and influential in establishing practical analog IC design.
-
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.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
