摘要： A transconductor input circuit for a down converting quadrature mixer stage of a direct-conversion receiver comprises a pair of common-gate input transistors whose source electrodes are coupled to a differential radio frequency (RF) input signal outputted from an interstage RF filter. The transconductor circuit further comprises a pair of equally-sized biasing transistors for biasing the pair of common-gate input transistors. Source electrodes of the biasing transistors are coupled to the source electrodes of the transistors to sense the differential radio frequency input signal for canceling intermodulation distortion.

摘要： A resonant load circuit is disposed in an integrated circuit, where the resonant load circuit includes an integrated inductance in parallel with an integrated capacitance, and further includes a first integrated resistance Rs in series with one of the inductance and capacitance, preferably in series with the inductance, and a second integrated resistance Rp in parallel with the inductance and capacitance. The first and second integrated resistances have values selected for reducing an amount of resonant load circuit Q over a plurality of instances of the integrated circuit. In a preferred, but non-limiting, embodiment the resonant load circuit forms a load in an RF low noise amplifier, such as a balanced inductively degenerated common source low noise amplifier (LNA).

摘要： The present invention relates to a resonator structure, temperature compensation method and temperature control apparatus for controlling local temperature of a resonator structure. At least one heating element (55) is integrated on a substrate of the resonator structure, and a temperature control signal generated based on a stored temperature characteristic is applied to the at least one integrated heating element (55). Thereby, the at least one heating element (55) and an optional integrated sensing element can be provided very close to the resonator. It is thus possible to control or calibrate variations of sensing elements, heating elements and resonator out from every sample.

摘要： A method for forming a spiral inductor (11) or component of a transformer, compatible with very large scale integrated processing, that achieves a higher Q value without occupying more space by splitting at least one turn (13 51) as two or more crisscrossing or interwoven smaller-width turns (13a 13b 52 53 54 55). The at least one turn (51) may, for example, be split into four turns paired up to provide two pairs of two turns, and the turns of each pair may then be interwoven or crisscrossed, and then the two pairs may also be interwoven or crisscrossed. The splitting of a turn into two or more smaller-width turns results in the current being divided among the smaller-width turns.
