摘要： The present invention discloses a distributed power amplifier topology and device that efficiently and economically enhances the power output of an RF signal to be amplified. The power amplifier comprises a plurality of push-pull amplifiers interconnected in a novel circular geometry that preferably function as a first winding of an active transformer having signal inputs of adjacent amplification devices driven with an input signal of equal magnitude and opposite phase. The topology also discloses the use of a secondary winding that matches the geometry of primary winding and variations thereof that serve to efficiently combine the power of the individual power amplifiers. The novel architecture enables the design of low-cost, fully-integrated, high-power amplifiers in the RF, microwave, and millimeter-wave frequencies.

摘要： The gain-bandwidth (GBW) limitation problem inherent in all amplifiers is overcome to provide wideband amplifiers with specified characteristics for the transfer function. Parasitic capacitances of transistors are absorbed or incorporated into the design of the passive networks, which are inserted between the gain stages of the amplifier. The component values are determined based on conventional low-pass filter structures. A prototype CMOS transimpedance amplifier implemented using the developed technique achieves over 9 GHz bandwidth and 54 dB transimpedance gain from a 0.5 pF photo-diode capacitance.

The second conductor first end is electrically coupled to the first conductor second end across the gap. At least one active element is configured to produce a self-oscillation current at a frequency f0. The self-oscillation current has a first direction in the first conductor and a second direction in the second conductor.

摘要： Systems and methods for constructing integrated three dimensional electromagnetic element arrays using a bulk resonator are illustrated. In several embodiments, the integrated three dimensional electromagnetic element arrays include electromagnetic elements buried within the bulk resonator. In many embodiments, inclusion of a third dimension in the electromagnetic element array can alleviate or eliminate the trade-offs that are experienced in conventional integrated antennas by using the third physical dimension to provide an additional degree of freedom to manipulate electromagnetic boundary conditions in the near-field of the substrate, affecting both the resulting electromagnetic near- and far-fields. In several embodiments, three dimensional electromagnetic element arrays are formed by mechanically stacking substrates on which integrated planar circuits are formed (i.e. chips) using conventional die stacking techniques.
