    摘要： Systems and methods for load detection on serial communication data lines are provided herein. In certain configurations, a serial communication system includes a data line having a load capacitance and a master device configured to generate a command signal for a slave device to measure the load capacitance on the data line. The system further includes a slave device including a load detector including a controller configured to receive the command signal from the master device, provide a first fixed current to the data line, determine an amount of time elapsed while the data line is driven to a first threshold value, and determine the load capacitance of the data line based on the amount of time elapsed.

    摘要： Power amplification system with adaptive bias control. In some embodiments a power amplification system includes a power amplifier including a radio-frequency (RF) input terminal for receiving an RF signal, an RF output terminal for providing an amplified RF signal, a supply voltage terminal for receiving a power amplifier supply voltage to power the power amplifier, and one or more bias terminals for receiving one or more bias signals. The power amplification system also includes a bias controller configured to provide the one or more bias signals to the one or more bias terminals, at least one of the one or more bias signals being based on the power amplifier supply voltage.

    摘要： Disclosed herein are wireless transceivers with switches to reduce harmonic leakage. In some embodiments, a transmitter system includes a power amplification system including a first power amplifier configured to amplify a signal at a first cellular frequency band and a second power amplifier configured to amplify a signal at a second cellular frequency band. The transmitter includes a switch coupled between an output of the second power amplifier and a ground potential. The transmitter includes a controller configured to, based on a band select signal, control the switch and selectively enable or disable each of the first power amplifier and the second power amplifier. Selective control of the switch can reduce harmonic leakage compared to a system that does not include the disclosed switches and controls.
