Homework
========

Continue with homework 9 and:

#. Evaluate the frequency characteristics of the asymptotic-gain, the loop gain and the servo function for the transmitter equipped with the `TLV4111 <https://www.ti.com/lit/ds/symlink/tlv4111.pdf>`_, designed to deliver 100mA peak into the transmit coil. Use SLiCAP to plot the frequency characteristics.

   - If the voltage drive capability, the midband accuracy and the bandwidth of the transmitter amplifier with the TLV4111, designed to deliver 100mA peak into the transmit coil are OK, finalize the transmitter design (prepare your poster).

#. Evaluate the frequency characteristics of the asymptotic-gain, the loop gain and the servo function for the receiver equipped with the `OPA209 <https://www.ti.com/lit/ds/symlink/opa209.pdf>`_, designed with a transmitter that delivers 100mA peak into the transmit coil. Use SLiCAP to plot the frequency characteristics.

   - If the noise, the midband accuracy and the bandwidth of the receiver amplifier with the OPA209, combined with the above transmitter are OK, finalize the receiver design (prepare your poster).
