    摘要: A method for fabricating a semiconductor device includes forming an SiGe region. The SiGe region can be an embedded source and drain region, or a compressive SiGe channel layer, or other SiGe regions within a semiconductor device. The SiGe region is exposed to an SC1 solution and excess surface portions of the SiGe region are selectively removed. The SC1 etching process can be part of a rework method in which overgrowth regions of SiGe are selectively removed by exposing the SiGe to and SC1 solution maintained at an elevated temperature. The etching process is carried out for a period of time sufficient to remove excess surface portions of SiGe. The SC1 etching process can be carried out at elevated temperatures ranging from about 25° C. to about 65° C.

    摘要: A symmetric Doherty amplifier includes a main amplifier and a peaking amplifier of the same size as the main amplifier. The symmetric Doherty amplifier is configured to operate at peak output power when the main amplifier and the peaking amplifier are each in saturation, and at output-back-off (OBO) when the main amplifier is in saturation and the peaking amplifier is not in saturation. Phase shift circuitry is configured to shift the phase at an output of the peaking amplifier at OBO so that a load impedance seen by the main amplifier and efficiency of the symmetric Doherty amplifier both increase at OBO as a function of the phase shift at the peaking amplifier output.

    摘要: A wideband Doherty amplifier circuit includes a main amplifier configured to operate in a linear mode, a peaking amplifier configured to operate in a non-linear mode and a Doherty combiner directly connected to an output of each amplifier so that no output match devices are in the path between the amplifier outputs and the Doherty combiner. The Doherty combiner is configured to present the same load impedance to each amplifier when both amplifiers are conducting and present a modulated load impedance to the main amplifier when the peaking amplifier is non-conducting so that a variation in the VSWR seen by the main amplifier is less than 5% over a plurality of frequency bands and/or so that the peaking amplifier has an off-state impedance spreading of 20 degrees or less over the plurality of frequency bands.

The main power amplifier has a high impedance load modulated state when the first and second peaking amplifiers are turned off. The three way wideband Doherty amplifier circuit further includes a constant impedance combiner connected to an output of each amplifier. The constant impedance combiner has a characteristic impedance which matches the impedance of the main amplifier in the high impedance load modulated state with or without an output matching device connecting the main amplifier output to the constant impedance combiner, as viewed from the output of the main amplifier.

    摘要: A circuit includes a power circuit and a current sensing circuit. The power circuit has a main current loop. The current sensing circuit is spaced apart from and electrically decoupled from the power circuit. The current sensing circuit is operable to generate a voltage proportional to an electromagnetic field generated responsive to a current change in the main current loop of the power circuit and generate a current information signal based on the voltage. The current information signal describes the current in the main current loop.
