摘要： The present invention includes an artificial intelligence system for acquiring real-time positioning and geographic data and generates a control signal received by a digital beam forming and steering system for adaptive detection, ranging, and tracking of moving objects for example vehicles. This system is particularly effective in detecting and tracking moving vehicles, obstacles and pedestrians on curved roads and blind spots behind corners of roads.

摘要： There are numerous types of dividers that have been employed at various frequency ranges. For many very high frequency ranges (i.e., above 30 GHz), dividers in CMOS have been developed. However, many of these designs use multiple stages. Here, however, a single stage divider has been provided that is adapted to operate at very high frequencies (i.e., 120 GHz). To accomplish this, it uses parasitic capacitances in conjunction with inductor(s) to form an LC tanks so as to take advantages of parasitics that normal degrade performance.

摘要： Traditionally, low-noise amplifiers or LNAs have been used in high frequency applications, but for very high frequency ranges (i.e., 60 GHz), building an LNA to meet performance needs has been difficult. Here, however, an LNA has been provided that operates well around 60 GHz. In particularly, this LNA is generally unconditionally stable, has a generally low noise factor or NF, and has a generally high gain around 60 GHz.

摘要： An oscillator circuit comprises a plurality of ring oscillators wherein each ring oscillator produces an oscillatory output signal. The ring oscillators are cross-coupled such that each ring oscillator drives only one other ring oscillator. In at least one embodiment, the oscillator circuit comprises four, three-stage ring oscillators. As such, each ring oscillator comprising three cells (e.g., inverters or delay elements). Further, in this embodiment, the oscillator circuit produces a four phase clock comprising the oscillatory output signals from each of the four ring oscillators.
