Thank you very much for your help.
I am considering a proximity sensor using LDC0851, and would like to know the following: LDC0851 is used in threshold mode with stacked coil.
Question 1: The "Differential LDC Core" shown in the internal block diagram of the LDC0851 is an oscillation circuit, and I imagine that it is an oscillation circuit in which the oscillation amplitude changes depending on the feedback current.
Question 2: The comparator between LSENSE and LREF compares the oscillation amplitude and the threshold value, but does this compare the feedback current?
Please tell me about "Differential LDC Core" in as much detail as possible.
