摘要： An amplifier having an active and passive gain stage connect to a load for driving a load according to a system analog input. A first embodiment of the amplifier in accordance with the present invention includes a logic network connected between a comparator network and a switching system, wherein the comparator network connects to the passive gain stage. Specifically, the active gain stage may include an active filter connected to receive an analog or digital input and provide a difference between the analog or digital input and the feedback signal relative to the gain factor of a gain unit connected to the active filter. The passive gain stage includes a passive filter. The logic network generates at least one switching signal which controls the switching system that includes at least one switching device to selectively provide power to the load. An output signal from the switching system provides output for the amplifier and is fed back to the active gain stage. In another embodiment, the output is a two-level signal and the passive and active filters are second order low pass filters, where the gain factor is about 25 or more. In yet another embodiment, the gain factor is approximately 250. Moreover, the amplifier may include a digital delta-sigma modulator connected to supply a two level input.

摘要： An antenna is provided. This antenna is contained within a package that is secured to an IC (which allows radiation to propagated away for a printed circuit board so as to reduce interference), and this antenna includes two loop antennas that are shorted to ground and that “overlap” and includes a “via wall.” With this configuration, circular polarization can be achieved by varying the relative phases of the input signals, and the “via wall” improves efficiency by reducing surface waves.

摘要： There are a variety of duty cycle systems, such as low noise amplifiers or LNAs, that have a large time varying current consumption, and parasitic inductances and resistance (usually from bondwires in the package) that can significantly affect supply currents. Thus, to compensate for these parasitics, a boost circuit is provided that allows for current to be supplied from a separate supply using a feedforward scheme to perform active decoupling.

摘要： A method for providing common-mode feedback is provided. A common-mode current is applied to a common-gate amplifier, and the common-mode current is sensed. In response to the sensed common-mode current, a control voltage is generated. A first feedback current (which is generated in response to the control voltage) can then be applied to differential ground of the common-gate amplifier if the common-mode current is less than a predetermined threshold. Additionally, a second feedback current (which is generated in response to the control voltage) can be applied to input terminals of the common-gate amplifier if the common-mode current is greater than the predetermined threshold.
