Abstract: PURPOSE: A low power and noise amplifier is provided to obtain a high power gain with a low power and improve a linearity. CONSTITUTION: The low power and noise amplifier has a cascode configuration having a common source transistor(M1) and a common gate transistor(M2) which are connected to each other in parallel. A common source transistor(M3) is connected to the common source transistor(M1) and the common gate transistor(M2) in series. Inductors(Lg,Ls) are used for an input impedance matching. An inductor(Ld) and a capacitor(C3) are used for an output impedance matching. A source of the common source transistor(M3) is bypassed by a bypass capacitor(C2). A signal is amplified by a gain of the cascode configuration. The amplified signal is inputted to a gate of the common source transistor(M3) so that the amplified signal is coupled and amplified by a capacitor(C1).
