Design active antenna

Discussion of the assignments

Assignment 7 (25pts)

Finalize the design of the active antenna with the ADA4817 operational amplifier.

  1. Verify the noise behavior:

    Replace the OpAmp with a ‘noisy nullor’ (SLiCAP LTspice symbol SLO_noise).

  2. Verify the biasing:

    Replace the OpAmp with a nullor with added input bias current sources and offset voltage and current sources (SLiCAP LTspice symbol SLO_dcvar).

  3. Verify the bandwidth:

    Use the SLiCAP model for the OpAmp for the evaluation of the dynamic response.

  4. If required: apply frequency compensation.
