Provided is a near field wireless communication apparatus that uses magnetic coupling and a method for operation of the apparatus, in which the magnetic coupling is used to transmit data or clock information with low power and high efficiency. A pulse generator of the near field wireless communication apparatus generates a pulse signal corresponding to transmission digital data to be transmitted. When the transmission digital data is '1,' the near field wireless communication apparatus modulates the data into the pulse signal and transmits the pulse signal. When the data is '0,' the near field wireless communication apparatus does not output the pulse.

An apparatus for stabilizing a boosted voltage includes a voltage detector, a buffer driver control unit and a buffer driver. The voltage detector detects a change in a level of a boosted voltage and outputs first through N-th detection signals corresponding to the detected change, the boosted voltage being generated to have a higher voltage level than a power supply voltage level in response to a clock signal. The buffer driver control unit generates first through 2N-th current control signals based on the first through N-th detection signals. The buffer driver includes first through N-th inverter drivers that selectively operate based on the first through 2N-th current control signals, thereby modulating a charging current for generating the boosted voltage. Hence, the boosted voltage having a constant level and a reduced ripple may be generated.
