A typical metal detector used for detecting buried coins, gold, or landmines consists of a circular horizontal coil assembly held just above the ground as shown in the figure to the right. Other uses of more specialized metal detectors include usage in medicine, security etc. Metal detectors have been used for diagnostic purposes since 1881.
Although this is done in most commercial and home made metal detector circuits, it is less than ideal. The main problem is that the voltage generated by the DC/DC converter is not ripple free, and especially at the high frequencies we are working with, this may cause some unwanted coupling. We will postpone this problem to the paragraph about ...
