in my proximity circuit am having the oscillator with the following specification that s my inductor coli may have the number of turns = 40,inductance = 38uH,capacitor = 820pF,..in practical while i checking my inductive sensor the oscillating frequency will be = 901 khz and the amplitude(peak to peak) of frequency will be approximately = 20 v.. if i bring the metal target in front of the sensor means the.. the amplitude of the frequency will get reduced.. so here how can i bring this same effect in oracd???
