Abstract:
1. A signal generator, comprising: an insulating substrate; a chip disposed on the insulating substrate and including an oscillator including a capacitance element determining a resonant frequency signal; a plurality of conductive lines disposed on the same surface of the insulating substrate to be spaced apart from each other; and a switch circuit connecting the plurality of conductive lines to the oscillator, the switch circuit including first switches that selectively connect or disconnect a first end and a second end of each of the conductive lines to the oscillator, and second switches that selectively connect or disconnect the plurality of conductive lines to each other, wherein at least one of the plurality of conductive lines is electrically connected with the oscillator and provides an inductance element determining the resonant frequency signal to the oscillator, the switch electrically connects at least some of the plurality of conductive lines to each other to form a loop having at least one turn, the chip includes at least one conductive coupling line, the at least one conductive coupling line is disposed on the same surface of the insulating substrate as the plurality of conductive lines, and at least some of the plurality of the conductive lines are electrically connected with the oscillator through the at least one conductive coupling line.
