    摘要: A semiconductor integrated circuit comprising a first circuit block including an oscillation circuit considered to be a noise generator and a second circuit block including circuits considered to be easily affected by a noise generated by the oscillation circuit, being most likely led to a malfunction are created on a single semiconductor substrate with the first and second circuit blocks separated from each other. To put it more concretely, the first and second circuit blocks are respectively created in a first island area and a second island area on the surface of the semiconductor substrate. The first and second island areas are each enclosed by an insulating isolation band. A low-resistance semiconductor area is created in a base area excluding locations occupied by active elements in the first and second island areas and is connected to a stable voltage terminal.

    摘要: An attenuating antenna switch may be used to suppress increase in the scale and power consumption of an RFIC. The antenna switch has a first terminal, a second terminal, and an antenna terminal coupled to the first and second terminals and configured to be connected to an antenna. The first switch switches between a first state in which a high frequency signal is propagated between the first terminal and the antenna terminal, and a second state in which the high frequency signal is interrupted. A second switch switches between the first and second states between the second terminal and the antenna terminal. The first and second switches are controlled in a mutually exclusive manner such that only one of the two switches can be in the first state at any given time. When in the first state, each switch adjusts an attenuation amount of the high frequency signal.

    摘要: A communication semiconductor integrated circuit device is capable of transmission in two or more different modulation modes and outputting transmission signals with less distortion. The communication semiconductor integrated circuit device comprises a gain variable amplification circuit which amplifies I-signals and Q-signals; and a mixer circuit which synthesizes the amplified I-signals and Q-signals and local oscillation signals to carry out modulation and frequency conversion. The communication semiconductor integrated circuit device is capable of transmission in two or more different modulation methods, for example, in GSM mode and EDGE mode. A low-pass filter of second or higher order is placed between the gain variable amplification circuit and the mixer circuit.

    摘要: As the gain control amplifiers for amplifying the reception signal, the step amplifiers are used. Two sets of these step amplifiers are provided and are then controlled to be used alternately. When switching of the gain occurs, after the gain is switched with the step amplifier not operated and offset is cancelled, the amplifier to which the reception signal is inputted is switched. Accordingly, the step amplifier can be used as the gain control amplifier for amplifying the reception signal to provide almost constant power consumption even when the gain is changed depending on the intensity of reception signal in the semiconductor integrated circuit device for communication to form a wireless communication system of dual-mode or more modes including the W-CDMA system. As a result, the operation life of battery, namely, the reception waiting period and communication period by single charging process can be expanded.
