    摘要: A linearizer and method. In a most general embodiment, the inventive linearizer includes a characterizer coupled to an input to and an output from said circuit for generating a set of coefficients and a predistortion engine responsive to said coefficients for predistorting a signal input to said circuit such that said circuit generates a linearized output in response thereto. In a specific application, the circuit is a power amplifier into which a series of pulses are sent during an linearizer initialization mode of operation. In a specific implementation, the characterizer analyzes finite impulse responses of the amplifier in response to the initialization pulses and calculates the coefficients for the feedback compensation filter in response thereto. In the preferred embodiment, the impulse responses are averaged with respect to a threshold to provide combined responses. In the illustrative embodiment, the combined responses are Fast Fourier Transformed, reciprocated and then inverse transformed. The data during normal operation is fed back to the data capture, corrected for distortion in the feedback path from the output of the amplifier, converted to basedband, synchronized and used to provide the coefficients for the predistortion linearization engine. As a result, in the best mode, each of the coefficients used in the predistortion linearization engine can be computed by solving the matrix equation HW=S for W, where W is a vector of the weights, S is a vector of predistortion linearization engine outputs, and H is a matrix of PA return path inputs as taught herein.

    摘要: A low-noise block converter comprises a low-noise amplifier, a local oscillator, a mixer, an IF-amplifier and a regulator. The low-noise amplifier amplifies a high-band received signal. The local oscillator generates a local-frequency signal. The mixer transforms the high-band received signal into an intermediate-frequency signal by mixing the high-band received signal with the generated local-frequency signal. The IF-amplifier amplifies the intermediate-frequency signal. The regulator is connected to the IF-amplifier to provide a steady current (or voltage) to the local oscillator, the mixer and the low-noise amplifier.

    摘要: Receiver signal strength indicator, having an automatic outputting detection circuit, can immediately detect whether its output terminals are connected to a specific apparatus or not. The RSSI comprises an RSSI signal generator, an A/D converter, an automatic outputting detection circuit and at least one output terminal. The automatic outputting detection circuit includes a current detection circuit and an interruption signal generator. When a current passes through the output terminal, the current detection circuit detects the occurrence of the current and generates a push signal. The push signal triggers the interruption signal generator, which in turn generates an interruption signal, and then an RSSI signals are output from the RSSI signal generator due to the interruption signal. The A/D converter converts the RSSI signal into an analog signal. Afterward, the analog signal is output to the exterior through the output terminal.

    摘要: An CMOS interconnection method that permits small source/drain surface areas has been provided. The interconnection is applicable to both strap and via type connections. The surface areas of the small source/drain regions are extended into neighboring field oxide regions by forming a silicide film from the source/drain regions to the field oxide. Interconnections on the same metal level, or to another metal level are made by contact to the silicide covered field oxide. The source/drain regions need only be large enough to accept the silicide film. Transistors with small source/drain regions have smaller drain leakage currents and less parasitic capacitance. A CMOS transistor interconnection apparatus has also been provided.

    摘要: The invention provides a process for depositing fluorinated amorphous carbon (a-F:C) films on IC wafers to provide a low-k interconnect dielectric material. The process, carried out in a PECVD chamber, introduces silane gas (SiH.sub.4) into the mixture of C.sub.4 F.sub.8 and CH.sub.4 gases used to deposit a-F:C films. The silane helps to decrease the fluorine etchants in the deposited film, helping to improve the crosslinks in the deposited product. Film produced in accordance with the present invention has both low-k, generally below 2.4, and high thermal stability, generally above 440.degree.

    摘要: A digital signal processor on an integrated circuit uses a multi-port data flow structure characterized by four ports, referred to as an acquisition port, two data ports, and a coefficient port. All four ports may be bidirectional so that data may be read from and written to the respective ports by the DSP system. This architecture allows a data flow management scheme in which data enters the processor through the acquisition port, or any one of the data ports. As the data is processed, it may ping pong between the data ports, or between a data port and the acquisition port. At the end of a DSP algorithm, the output data may be provided through the acquisition port or a data port as suits the needs of the particular application. A coefficient port is typically used for providing coefficients or twiddle factors for DSP algorithms. A DSP system is provided which includes a digital signal processor having four ports as discussed above. Each data port is attached to dedicated, independent data memory. This provides for optimization of multipass algorithms.
