    摘要： An apparatus of a hybrid power modulator using interleaving switching is provided. The apparatus includes a linear switching unit for generating an output signal by comparing an envelope input signal and a feedback signal, an interleaving signal generator for generating an interleaving switching signal arranged not to supply the signal to input stages of P-type Metal-Oxide- Semiconductor (MOS) Field Effect Transistors (FETs) and N-type MOS FETs of power cells at the same time by comparing the output signal and a reference signal, and a switching amplifying unit for determining a level of the switching signal using the interleaving switching signal. Hence, the hybrid power modulator using the interleaving switching method in the envelope signal of the wide bandwidth maintains high efficiency and high linearity. In addition, the buck converter can use the single inductor by preventing the simultaneous on/off of the power cells.
