  • Patent number: 9846446
    Abstract: Disclosed are a temperature compensation apparatus and method. The apparatus includes a reference signal generator that supplies at least one of a first current which is constant regardless of temperature variation and a second current which is proportional to temperature variation, a slope amplifier that determines a first output current having a second temperature coefficient which is a multiple of a first temperature coefficient of the second current, based on the first current and the second current, and a slope controller that determines a second output current having a third temperature coefficient, using a weighted average of the first current and the second current.
    Type: Grant

  • Patent number: 9748912
    Abstract: Provided is a Radio Frequency (RF) communication apparatus and a method for detecting power. The RF communication apparatus includes a receiver that receives a segment value indicating one of multiple transmission output power ranges, a power detector that detects a strength of an RF transmission signal in an output power range corresponding to the segment value, and a transmitter that transmits the strength of the detected RF transmission signal. The power detector includes a feedback unit that receives the fed-back RF transmission signal, an RF core unit that generates a Root Mean Square (RMS) of the RF transmission signal, and a converter that converts a current signal corresponding to the RMS of the RF transmission signal into a voltage signal, and converts the converted voltage signal from a differential signal to a single signal.
