Abstract
A low-noise differential bias circuit is provided which obtains excellent noise characteristics while ensuring excellent distortion characteristics. A collector of a transistor Qis connected to a voltage supply point (Vcc) via a resistor R. A base of the transistor Qis connected to a base of a transistor Qvia resistors R, Rconnected in series. A connection point between the resistors R, Ris connected to the collector of the transistor Q. A collector of a transistor Qis connected to the voltage supply point at connection point A via a resistor R. A base of the transistor Qis connected to a base of a transistor Qvia resistors R, Rconnected in series. A connection point between the resistors R, Ris connected to the collector of the transistor Q. By this configuration, a high frequency ground is performed at the connection point A.
