  • Publication number: 20230023111
    Abstract: Apparatus and methods for biasing of low noise amplifiers (LNAs) are provided herein. In certain embodiments, an LNA includes at least one transistor that amplifies a radio frequency (RF) input signal, and a bias circuit including a current bias circuit that generates a bias current based on a reference current and a voltage bias circuit that generates at least one input bias voltage for the at least one transistor based on the bias current. The current bias circuit includes a first bias transistor that receives the reference current, a second bias transistor that generates the bias current, and an amplifier that controls a first bias voltage of the first bias transistor to match a second bias voltage of the second bias transistor.

  • Publication number: 20080223817
    Abstract: A bottle assembly includes a bottle that has a liquid container, a neck portion that extends from the liquid container and a mouth that is adapted to dispense liquid, and a cup assembly having a cylinder that has an open top end, a closed bottom end and a cylindrical wall, and a cap that is integrally provided at the closed bottom end. The cap has an engaging portion that is adapted to engage with the mouth of the bottle. The cylindrical wall of the cup assembly is tapered. The bottom end is substantially thicker than the cylindrical wall. The bottom end has a hollow portion that surrounds the cap. The engaging portion has a female threaded portion that is adapted to engage with a male threaded portion of the mouth of the bottle.
