RF oscillator uses current feedback
op amp: 10/03/2002 EDN -
Design Ideas / A current-feedback amplifier is a
well-known component with many uses. Its basic block
diagram shows that its input stage is a voltage
follower—in practice, a symmetrical emitter follower
(Figure 1). The configuration samples the output
current, converts it to voltage across a large
impedance, and amplifies it to the output using a
high-power, low-output-impedance amplifier..
