Abstract
The oscillation method uses an oscillation circuit in which a plurality of MOSFETs are annularly connected. The method comprises the steps of: forming GND of the circuit, which is separated from GND of a driving electric source of the MOSFETs, in a part of a first connection line which connects the MOSFET with the adjacent MOSFET; connecting a probe with a second connection line which connects another MOSFET with the adjacent MOSFET, an odd number of the MOSFETs being connected between the GND and the second connection line; and generating an oscillation waveform between the probe and the GND.
