OPERATING MODE

Between terminals A and E, the integrated circuit

acts like a negative resistance equal to the external

resistor R1 connected between terminals B and H.

The oscillation stops when loss resistance Rp of

tuned circuit becomes smaller than R1. Then, the

The oscillation sustains when loss resistance Rp of

tuned circuit becomes higher than R1. Then, the

Eddy currents induced by coil L1 in a metallic body,

determine loss resistance Rp.
