摘要： Embodiments include methods, systems, and apparatuses capable of dynamically and adaptively operating on wideband signals. Examples include state variable filters whose center frequencies can be tuned using variable gain blocks coupled to outputs of filter integrators. First- and second-order state variable filters may operate on signals in parallel and their outputs combined to produce a filtered output. Filters may be tuned to pass or reject signals depending on the application; sample applications include, but are not limited to: agile filtering; spectrum analysis; interference detection and rejection; equalization; direct intermediate-frequency transmission; and single-sideband modulation and demodulation.

摘要： Broadband analog radio-frequency devices can be used to create building blocks for scalable analog signal processors that operate over bandwidths of 50 MHz to 20 GHz or more. Example devices include integrators (transconductors), digitally controlled attenuators, buffers, and scalable summers implemented using deep sub-micron CMOS technology. Because the devices are implemented in CMOS, the ratio of trace/component size to signal wavelength is about the same as that of low-frequency devices implemented in printed circuit boards. Combining this scaling with high gain/high bandwidth enables implementation of feedback and programmability for broadband analog signal processing.

摘要： Mobile phone handsets include a CMOS front end configured for operating across multiple transmit and receive frequencies. The front end typically includes multiple receivers, each covering a different band allocated for cellular service, and requires large, expensive and power-intensive A/D converters and DSPs. Front-end circuits disclosed herein operate with a broadband software-defined radio (SDR), and include a receive Low Noise Amplifier (LNA), transmit Power Amplifier (PA), and an antenna matching network. The front-end provides broadband operation using relatively low power, and minimizes noise in the received signal.

摘要： A biquad wideband signal processing circuit can operate over bandwidths of 50 MHz to 20 GHz or more. The biquad circuit employs a configuration of integrators (transconductors), buffers, and scalable summers that can be implemented using deep sub-micron CMOS technology. Combining this scaling with high gain/high bandwidth enables implementation of feedback and programmability for broadband analog signal processing. A biquad circuit implementing a number of parallel integrator lines having adjustable gain provides greater accuracy, stability, and bandwidth, and allows for control of process variations and temperature variation in real-time.

摘要： Apparatus and methods for vector inductors are provided herein. In certain configurations, an apparatus includes a vector inductor comprising a plurality of conductors arranged in a stack and separated from one another by dielectric. The conductors are tightly coupled to one another to provide a relatively high amount of mutual inductance. For example, adjacent conductors in the stack can be mutually coupled with a coupling coefficient k that is at least 0.5, or more particularly, 0.9 or greater. In certain implementations, the conductors are electrically connected in parallel with one another to provide the vector inductor with low resistance. However, tight coupling between the conductors in the stack can result in vector inductor having an overall inductance that is similar to that of a self- inductance of an individual conductor in the stack. The Q-factor of the vector inductor can be increased by the inclusion of additional conductors in the stack.
