摘要： A first signal conditioning circuit is formed from a first portion, a second portion and a third portion. Signal conditioning functions of each of these portions are facilitated by a predetermined type of integrated semiconductor die within which they are formed. Two different semiconductor dies are thus provided for facilitating integration of the first through third signal conditioning portions therein. Wire bonds are provided between the two different semiconductor dies in order to form circuit paths between the different first through third portions. The signal routing using between the two different semiconductor dies provides for completing of the first signal conditioning circuit having a first signal conditioning function. For example, circuits such as interstage matching circuits are disposed on a different semiconductor die than power amplifier circuits.

摘要： A power detector for measuring the power transfer between a circuit for emitting an electrical signal and a first conductor that receives the emitted electrical signal. The emitted signal causes a magnetic field to be generated in the first conductor. A coupling detection circuit measures an electric current that arises in a second conductor that is proximate and electrically coupled to the first conductor. The measured electric current in the second conductor is used to determine the power transfer between the emitting circuit and the first conductor. The first and second conductors can be bond wires within an integrated circuit package, and the coupling detection circuit can be disposed in a semiconductor substrate within the integrated circuit package.

摘要： Optical receiver modules are used for receiving high-speed optical data signals. Unfortunately, these optical receiver modules are often tested for the first time after they are packaged in a housing. Thus significant costs are associated with those packaged devices that fail to meet predetermined criteria. An integrated optical receiver module is proposed that has an optical detector direct attached, or flip-chipped or bumped, onto an integrated circuit having an amplifier circuit. The direct attach process is performed when the integrated circuits still reside on a semiconductor wafer prior to dicing thereof. Thus, high speed optical testing of the optical receiver module is possible on a wafer level to determine actual performance characteristics thereof prior to dicing.

摘要： The gain and current consumption of a power amplifier are adjusted while maintaining amplified output signal linearity. Where linearity and low power consumption are maintained for the amplifier by controllable shunting (25, 28) of an output signal amplitude and by providing a predetermined bias signal (18) to the amplifier circuit in a precalibrated manner. A mapping circuit (23) is disposed for receiving a control signal (20) and for providing the predetermined bias signal to the amplifier circuit in the precalibrated manner. The mapping circuit is either internally provided within the same circuit as the power amplifier, or externally.

摘要： Recent trends have seen the desire for lower and lower supply voltages in radio frequency (RF) components as this leads to lower power consumption and, therefore, longer battery life. As well, lower voltages and less current means that mobile products can be made to require fewer battery cells leading to lighter, more compact devices. The present invention discloses a novel topology for providing a low-voltage voltage-controlled oscillator (VCO). The novel topology is based on the negative transconductance oscillator. However, the novel topology of the invention eliminates transistor "stacking" in the oscillator circuit, thereby allowing the oscillator circuit to be operated at a supply voltage only slightly higher than the turn-on voltage for a single transistor.
摘要翻译：最近的趋势已经看到了射频（RF）组件中电源电压越来越低的愿望，因为这导致更低的功耗并因此延长电池寿命。同样，较低的电压和较少的电流意味着移动产品可以被要求更少的电池单元，从而导致更轻，更紧凑的设备。本发明公开了一种用于提供低压压控振荡器（VCO）的新型拓扑结构。新颖的拓扑结构基于负跨导振荡器。然而，本发明的新颖拓扑消除了振荡器电路中的晶体管“堆叠”，由此允许振荡器电路在仅比单个晶体管的导通电压略高的电源电压下工作。

摘要： An electronic module that operates at various radio frequency standards is provided. The module includes a first integrated circuit die formed in a first semiconductor substrate and manufactured using a first semiconductor process. Disposed within the first integrated circuit is the first signal conditioning circuit for performing a function and the first and second ancillary circuits. The first ancillary circuit electrically coupled to the first signal conditioning circuit for use by the first signal conditioning circuit during operation thereof. The second ancillary circuit is for other than being used by the first signal conditioning circuit during operation thereof since the second integrated circuit die is electrically coupled to the second ancillary circuit and formed in the second semiconductor substrate and co-located with the first integrated circuit within the module. The second integrated circuit die benefits from the operation of the second ancillary circuit for functioning thereof for performing a similar function to the first signal conditioning circuit.
