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.

In one implementation, a signal handling apparatus (100) includes an input impedance transformer (102) for receiving an input signal and matching an internal apparatus impedance, a splitter (104) for providing N split signals, a number of signal processing circuits (110; 112-1,..., 112-m) for processing the N split signals, a combiner (120) for combining the N split signals into a combined signal, and output impedance transformer (122) for receiving the combined signal and for matching the internal apparatus impedance to an output impedance of the apparatus. The apparatus may provide filtering, duplexing and other radio frequency signal processing functions. A tunable duplexer may be implemented using a vector inductor and tunable capacitor array with frequency dependent impedance transformers.

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.

摘要： Apparatus and methods for variable capacitor arrays are provided herein. In certain configurations, an apparatus includes a variable capacitor array and a bias voltage generation circuit. The variable capacitor array includes a plurality of metal oxide semiconductor (MOS) variable capacitor cells, which include one or more pairs of MOS capacitors (121,122,123,124) implemented in anti-parallel and/or anti-series configurations. In certain implementations, the MOS variable capacitor cells are electrically connected in parallel with one another between a radio frequency (RF) input and an RF output of the variable capacitor array. The bias voltage generation circuit generates bias voltages (VBl, VB2) for biasing the MOS capacitors of the MOS variable capacitor cells, such that the voltage coefficient of capacitance is kept low and non-linearities in the circuit are reduced.

摘要： A highly linear, variable capacitor array (400) constructed from multiple cells (100-0, 100_ 1,... 100_ N). Each cell includes a pair of passive, two-terminal capacitor components connected in antiparallel. The capacitor components may be Metal Oxide Semicondutor, MOS, capacitors. A control circuit (410) applies bias voltages (411_0, 411 1,... 411_ N) to bias voltage terminals associated with each capacitor component, to thereby control the overall capacitance of the array. The two capacitors in each cell are connected in anti-parallel to reduce the cell's and the array's voltage coefficient of capacitance. MOS capacitors are preferably operated in inversion or accumulation mode.

摘要： A multi-stage signal handling circuit. Operating as a combiner or splitter, first stage transformers match low input impedance at a first set of differential terminals, and second stage transformers match expected higher impedance at second terminal(s). Transformer windings are mirror image, vertically aligned, meandering conductive tracks disposed on opposite sides of a PCB. Air columns above or below the conductive tracks reduce ground plane effects. A capacitor provided across the differential input terminals of each transformer is chosen to further match the power amplifier output, including consideration of inherent inductance presented by the circuit tracks and vias between transformer sections.
