Magnetoelectric sensor concepts typically require magnetic or electrical excitation signals with an accurate frequency and amplitude for operation at their particular resonance frequency. This work compares two digital designs for generating the electrical signal that drives the composite ME sensors. The first one includes a Variable-Content Look-Up-Table Single-Side-Band modulation and the second one is a Direct-Digital-Synthesizer implementation. Empirically determined quantitative parameters were used to compare the estimated quality of the signals and the achievable frequency resolution for both implementations. The Direct-Digital-Synthesizer was converted to gate-level-netlist to simulate power and area consumption in a CMOS-180nm.
