Abstract: PURPOSE: A low noise amplifier and a radio receiver are provided to greatly improve linearity by using the body biasing and complementary superposition of a transistor. CONSTITUTION: A low noise amplifier is composed of a complementary common source low noise amplifier(100) linearized. The linearized complementary common source low noise amplifier comprises a first primary transistor part(110), a first subsidiary transistor part(120), and a capacitor(130) for simultaneously matching optimal noise and input impedance. The first primary transistor part comprises a first NMOS(N-Channel Metal Oxide Semiconductor) transistor, a first PMOS(P-Channel Metal Oxide Semiconductor) transistor, and resistance. The first subsidiary transistor part includes a first NMOS transistor of the first primary transistor part and transistors parallely connected to the first PMOS transistor. The capacitor for simultaneous matching is communally connected to output terminals of the first primary transistor part and the first subsidiary transistor part.

Abstract: PURPOSE: An apparatus and a method for detecting the transformation of a developable surface are provided to effectively detect the cubical transformation of a soft plane-type object that can be developed to a plane. CONSTITUTION: An apparatus for detecting the transformation of a developable surface comprises a plurality of bending sensors(120), a detection circuit(130), and a processor(140). The bending sensors are arranged at regular intervals along the edge of a developable surface(110) as being divided into two triangle regions that hold one side in common. The detection circuit detects a transformation value according to the transformation of each bending sensor. The processor estimates the transformation of the developable surface according to the transformation values outputted from the detection circuit.
