摘要： A wireless power receiver receives electrical power via electromagnetic field coupling from a wireless power transmitter. During communication time periods, the power receiver alters the electromagnetic field in a manner that the power transmitter can detect as a string of logic bits in a communication bit stream for sending data to the power transmitter. During pause time periods when data is not being sent to the power transmitter, the power receiver alters the electromagnetic field in a manner that the power transmitter does not detect as a string of logic bits (e.g. at a rate outside a communication frequency band). In some embodiments, a ripple is reduced in a voltage produced by the wireless power receiver from the electromagnetic field during the communication and pause time periods.

摘要： A code-controlled voltage divider (20) is disclosed. The voltage divider (20) includes an upper portion with a resistor (22) and a dummy switching transistors (23), which is biased to be in an on-state. A lower portion of the voltage divider (20) includes multiple parallel legs, each including a resistor (24) and a corresponding switching transistor (26) that has its gate receiving one bit of a digital control word. A decoder (30) may be provided within the voltage divider (20) to generate the digital control word from an incoming code word, for example from a central processing unit (10). The lower portion resistors (24) of the voltage divider (20) are binary-weighted, and the sizes of the corresponding switching transistors (26) are binary-weighted so that the portion of the series resistance of each parallel leg that is due to the on-resistance of the switching transistor (26) is substantially constant over all of the parallel legs. The upper resistor (22) has a resistance that is related to one of the resistors (24) in the lower portion, and the size of the dummy switching transistor (23) is similarly related to the switching transistor (26) to that resistor's switching resistor (24).
