    摘要: An on-chip resistance to an input current of an input signal includes a parallel transistor resistor and a control circuit for biasing the transistors of the parallel transistor resistor. The parallel transistor resistor includes first and second transistors of first and second types. Each transistor includes first and second current handling terminals and a control terminal. The control terminals are coupled to receive control signals from the control circuit. The first current handling terminals are coupled to provide an input node for receiving an input signal, and the second current handling terminals are coupled to provide an output signal. The control circuit is coupled to provide the first and second control signals for biasing the respective first and second transistors so that a first derivative of a resistance of the parallel transistor resistor in relation to an input-to-output voltage is zero at a selectable operation point.

    摘要: A method and apparatus permit handling of unwanted calls from callers such as telemarketers, when caller identification is provided. In one embodiment, the called party adds the caller identification information for the telemarketer to a personal list after receiving the unwanted call. Subsequent calls from the telemarketer are intercepted. In a second embodiment, the called party identifies the telemarketer by detecting the caller identification information before answering the call. By providing a screen listing indication, the caller identification information is added to the called party's personal list before the call is completed, permitting the call to be intercepted and while future calls from the telemarketer to be intercepted.

    摘要: One embodiment of the present invention provides an inductor with a variable inductance within a semiconductor chip. This inductor includes a primary spiral composed of a conductive material embedded within the semiconductor chip to provide a source of variable inductance. It also includes a control spiral composed of the conductive material vertically displaced from the primary spiral in neighboring layers of the semiconductor chip. This control spiral is magnetically coupled with the primary spiral so that changing a control current through the control spiral induces a change in inductance through the primary spiral. The inductor also includes a controllable current source coupled to the control spiral that is configured to provide the control current. One embodiment of the present invention includes a core surrounding the primary spiral and the control spiral in the semiconductor chip. This core is comprised of a core material with a magnetic permeability that facilitates magnetically coupling the control spiral with the primary spiral. In a variation on this embodiment, the core material includes a high frequency ferrite that operates at a frequency above one gigahertz without resistive eddy losses that substantially prevent a magnetic coupling between the control spiral and the primary spiral. In a variation on this embodiment, the high frequency ferrite can include NiZn.
