We present two circuit concepts for the inductive excitation and signal reception of magneto-mechanical resonators, which are integrated into a transmit-receive signal chain. The focus is on comparing the concepts with respect to their ability to deliver power at different frequencies and to receive signals. Additional necessary components of the signal chain are illustrated for the full system context but not analyzed in detail. Instrumentation and design aim to be scalable for multi-channel arrays, using either off-the-shelf class-D audio amplifiers or a custom H-bridge.enTechnology::620: EngineeringConference Paper10.1109/sensors59705.2025.1133097910.5281/zenodo.14764827Conference Paper
