Abstract: A wideband power amplifier (PA) linearization technique is proposed. A current interpolation technique is proposed to linearize power amplifiers over a wide bandwidth. The wideband power amplifier linearization technique employs a novel transconductance Gm linearizer using a current interpolation technique that achieves improvement in the third order intermodulation over wide bandwidth for a sub-micron CMOS differential power amplifier. By using a small amount of compensating bias into an opposite phase differential pair, linearization over wide bandwidth is achieved and can be optimized by adjusting the compensating bias.

Abstract: A micro-cluster water distiller and a water cluster refiner thereof are used to solve the problem where the currently available water distillers cannot refine the water clusters. The micro-cluster water distiller includes a body having a water outlet; a hot water tank disposed in the body and configured to receive and heat water to produce vapor; a cooling module disposed in the body and including a condensing tube and a water outlet tube, with a head end of the condensing tube intercommunicating with a top of the hot water tank, with a terminal end of the condensing tube intercommunicating with a head end of the water outlet tube, with a terminal end of the water outlet tube intercommunicating with the water outlet; and a water cluster refiner including a permanent magnet disposed on the water outlet tube, with the permanent magnet having a magnetic field of 3000-5000 Gs.

Abstract: A water distiller includes a shell, a container, a heater, a thermal conductive plate, a thermostat, a cover, a condenser coil, and a fan. The shell provides a compartment for receiving the container, the heater, the thermal conductive plate, and the thermostat. The container includes a bottom wall with an inclined surface to which the heater is connected. A higher end of the inclined surface is connected to the thermal conductive plate and the thermostat. The thermostat is mounted in a room provided between the shell and the container, and a first spring is provided to bias the thermostat to be in an intimate contact with cylindrical side wall of the container. A cap is mounted outside the room and a push button is mounted in the cap with an end exposed outside the cap for manual operation. A second spring is mounted in the cap for biasing the push button to a position for the manual operation. The cover mounted on top of the shell provides a compartment for receiving the condenser coil and the fan.

Abstract: A liquid distiller. The distiller includes a main body having a main housing inside which water is heated to generate steam. The steam is passed through a condenser. A fan is positioned inside the distiller to supply cool air to the condenser. A water output is defined in the main body. Air inlets are defined in a outer periphery of the main housing. An upper lid is mounted on top of the main body and includes an air outlet in an upper side thereof so as to guide air which has passed around the condenser to dissipate out of the main body. An air guide is securely mounted between the upper lid and the main body. The air guides includes a disc with a central opening, an upper tubular member projecting upwardly from an upper side of the disc and having a first through hole communicating with the central opening of the disc, and a lower tubular member projecting downwardly from an underside of the disc and having a second through hole communicating with the central opening of the disc.
