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.

Abstract: An ultrasound imaging method and apparatus forms high-quality color ultrasound images by using variable power threshold levels depending on pixel position. The method comprises the steps of determining a power threshold level that is varied depending on a noise, transmitting ultrasound signals from at least one transducer array to a target object, receiving a first signal including a signal reflected from the target object mixed with a noise, and imaging an ultrasound image of the target object corresponding to the first signal when the power level of the first signal is greater than the variable power threshold level. The apparatus comprises one or more transducers for transmitting an ultrasound signal to an object and receiving a first signal including a reflected signal from the object mixed with a noise; and a digital signal processor for forming an ultrasound image of the object corresponding to the first signal when a power level of the first signal is greater than a variable power threshold level.

Abstract: An ultrasound diagnostic apparatus and method for measuring a blood flow velocity effectively select one of the positive frequency range and the negative frequency range to compute noise threshold, and determine a reliability of the computed noise threshold. A sample data generator samples a reflected signal of the ultrasound signal transmitted into a human body. A frequency distribution data generator processes the sample data, and generates a frequency distribution data including a number of frequency components. A first determiner selects one of a positive frequency range and a negative frequency range of the frequency distribution data. A second determiner determines a noise threshold by using a predetermined number of frequency components within the frequency range selected by the first determiner. A third determiner determines a peak frequency component having the highest frequency among the frequency components.
