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.. |
