[This AI generated description is only partially accurate. A more accurate one will be provided] I have two separate LC tanks that must run in lock-step at around 50kHz. The goal is to keep their resonant frequencies matched to within roughly ±20 Hz while they drift with temperature, load, and component ageing. What I already have: • The basic LC topologies for each resonator. • Direct access points for sensing voltage or current in each tank. • A rough block-diagram concept that suggests using either an analogue phase detector with a varactor tuner or a small MCU driving a DDS/PLL loop, but I am open to better ideas. What I need from you: 1. A concrete circuit-level design that continually measures the two tanks and adjusts one (or both) so their peaks coincide wi...
