Electric circuit fragment with transmit/receive switch topology

A detector system for one or more of tracking and/or sensing for a micro-magnetic resonator, the detector system comprising:

• an electric circuit that comprises the electric circuit fragment, and
• a ferromagnetic object, wherein
• the electric circuit fragment is arranged and configured for generating an oscillating magnetic field in its transmit state to excite a mechanical resonance of the ferromagnetic object such that the ferromagnetic object generates an external oscillating magnetic field that can be detected by the electric circuit fragment in its receive state.

A method of operating the electric circuit fragment comprising:

• switching the first switch into its conductive state to shorten the low noise amplifier and switching the second switch into its isolating state, for bringing the electric circuit fragment into its transmit state, and
• switching the first switch into its isolating state and switching the second switch into its conductive state to ground the power amplifier output for bringing the electric circuit fragment into its receive state.

A computer program for controlling an electric circuit fragment, the computer program comprising program code for causing the electric circuit fragment to switch from its transmit state into its receive state or vice versa.

A detector system for a micro-magnetic resonator, the micro-magnetic resonator used for one or more of:

• tracking, sensing, wireless remote tracking, wireless remote sensing, the detector system comprises one or more ferromagnetic objects that can mechanically oscillate upon excitation of a ferromagnetic object's mechanical resonance by applying an oscillating magnetic field, and the detector system is configured to detect and examine a received an external oscillating magnetic field coming from the mechanical oscillation of the ferromagnetic object, wherein the detector system further comprises an electric circuit with an electric circuit fragment, wherein the electric circuit fragment is arranged and configured for generating an oscillating magnetic field in the transmit state for excitation of a mechanical resonance of the ferromagnetic object.
