    Abstract: PROBLEM TO BE SOLVED: To provide a level conversion digital switch exhibiting a relatively small component element count, having the smallest die region and saving power supplying current.
    SOLUTION: The level conversion digital switch provides changeover and level conversion between a first system and a second system which operate under logic supply voltage different in changeover element. When the supply voltage of the first system is greater than that of the second system, the changeover element is driven under voltage lower than the logic supply voltage of the first system. The level conversion digital switch includes the changeover element and a drive circuit. The changeover element provides a bidirectional signal path between the first system which operates under a first logic supply voltage and the second system which operates under a second logic supply voltage. The drive circuit includes a voltage selection section which generates the second supply voltage lower than the first logic supply voltage and a control section which operates under the second supply voltage to generate control voltage for the changeover element with control voltage lower than the first logic supply voltage.

    Abstract: PURPOSE: A control method of a motor driving system is provided to improve the performance of a motor driving system by preventing oscillatory behaviors in the motor driving system. CONSTITUTION: A test driving signal is applied to the motor of a machine system in order to generate oscillatory behaviors in the machine system. A backchannel electric signal due to the motor of the machine system is detected from the oscillatory behaviors. The resonant frequency of the machine system is calculated from the backchannel electric signal. The resonant frequency of the machine system is saved in a register(910~930). The resonant frequency of the machine system is used in a run time mode.
