A reconfigurable processor (RP) structure is provided, and particularly, a multi-mode providing apparatus including an exclusive coarse-grained array unit for each mode and a multi-mode providing method thereof are provided. The multi-mode providing apparatus includes: at least one reconfigurable operation mode execution unit performing a plurality of operations for processing a predetermined operation mode; a common coarse-grained array unit shared temporally by the at least one reconfigurable operation mode execution unit, and performing a main processing operation set to be performed by the common coarse-grained array unit, among the plurality of operations; and a controller determining whether the common coarse-grained array unit is available, and according to the result of the determination controlling the at least one reconfigurable operation mode execution unit so that the common coarse-grained array unit or an exclusive coarse-grained array unit performs the main processing operation, the exclusive coarse-grained array unit included in the at least one reconfigurable operation mode execution unit. Therefore, it is possible to reduce a delay time for data processing while reducing the size of hardware.

Reconfigurable apparatus and method for providing multiple modes

Provided is a multiband low noise amplifier including a first transistor, an input matching circuit, and a first capacitor. The first transistor includes a collector electrically connected to a first power supply, a grounded emitter, and a base connected to the other end of a first inductor having one end as an input end of the low noise amplifier. The input matching circuit is connected between the collector and the base of the first transistor. The first capacitor connected to the collector of the first transistior. The input matching circuit includes a varactor. The input matching circuit includes a second capacitor connected to the varactor. The input matching circuit includes a first resistor connected to the varactor. In the multiband low noise amplifier, a varactor having a variable capacitance is installed at an input end, thereby easily performing band switching through bias voltage control by a small amount and minimizing noises that may be caused by a control signal.
