Abstract: Disclosed is a broadcast receiver that includes an antenna connector configured to connect with an antenna for receiving a broadcast signal including broadcast content. The broadcast receiver also includes a signal processor configured to generate a reference signal having a strength corresponding to a signal input through the antenna connector and to process the generated reference signal to output an image signal for displaying the broadcast content, and a controller configured to determine whether the antenna is connected to the antenna connector based on an output value of the reference signal and to perform subsequent operations related to whether the antenna is connected based on the determination.

Abstract: An analog front-end (AFE) circuit has at least one AFE stage to generate a conditioned analog signal, and a gain control block to set a gain of the AFE stages. A finite state machine (FSM) block sets the gain to a baseline set gain without gain compression, or a current set gain with gain compression. An amplitude block determines amplitudes of the inner and outer eyes of a signal eye of the conditioned analog signal at the baseline set gain and the current set gain. A compression calculation block determines a gain compression of the conditioned analog signal at the current signal gain based on the relative changes in the respective amplitudes of the inner and outer signal eyes between the baseline and current set gains. The FSM block increases the current set gain until the gain compression ratio reaches a predefined limit.

Abstract: Various embodiments are directed to systems and techniques for reducing power consumption in a mobile computing device. In one or more embodiments, a mobile computing device may be arranged to determine a user environment based on detected antenna impedance or detected current. After the user environment is determined, the mobile computing device may confirm that total radiation power (TRP) for the mobile computing device at an initial conducted power level exceeds the minimum TRP threshold required by the network carrier to receive acceptable quality of service (QoS). Based on the excess TRP for the particular user environment, the mobile computing device may determine a reduced conducted power level to be input to an antenna system. Accordingly, significant power savings may be achieved. To save additional power, the mobile computing device may automatically adjust and/or improve antenna impedance matching based on user environment allowing a further reduction in conducted power.

Abstract: One embodiment of the present subject matter includes a method of receiving an input signal. The method, in various embodiments, includes detecting a peak of the input signal and detecting an envelope of the input signal. In various embodiments, the peak and envelope are used to identify out-of-band blocking signals and to adjust gain control. The method also includes comparing the peak to a first threshold Tp and comparing the envelope to a second threshold Te. In the method, if the peak is above the first threshold and the envelope is below the second threshold, then ignoring the input signal. If the envelope is above the second threshold, the method includes applying automatic gain control to decode information encoded in the input signal.

Abstract: In a high frequency power amplifier circuit in which bias voltages are applied to the transistors for amplification by current mirroring, this invention enables preventing waveform distortion near the peak output power level by allowing sufficient idle currents to flow through the transistors for amplification, while enhancing the power efficiency in a low output power region. The power amplifier includes a detection circuit comprising a transistor for detection which receives the AC component of an input signal to the last-stage transistor for amplification at its control terminal, a current mirror circuit which mirrors current flowing through that transistor, and a current-voltage conversion means which converts current flowing in the slave side of the current mirror circuit into a voltage. In the detection circuit, a voltage from a bias circuit for generating the bias voltages for the transistors for amplification is applied to the control terminal of the transistor for detection and output of the detection circuit is applied to the control terminal of the last-stage transistor for amplification.
