Latest Patents
Ehrenreich's latest patents include an "Automatic power level control circuit for a transceiver device." This invention provides output power control for a transmitter device used in wireless LAN applications. The circuit detects an output signal and adjusts a corresponding control voltage of a DAC in the baseband section. The measurement of output power occurs during the first transmit cycle, with adjustments made before the next cycle begins. This method ensures reliable output level control with minimal radio frequency components, enhancing stability through time-discrete control operations.
Another significant patent is the "Integrated RF signal level detector usable for automatic power level control." This invention determines the radio frequency signal level by generating an AC reference voltage from a DC reference voltage. The envelope of the AC reference voltage is detected using an envelope detector, which is designed similarly to the one used for the RF signal. This approach effectively eliminates DC offset, providing high immunity against temperature and power supply variations. By utilizing the same RF signal path for both the RF signal and the reference signal, the invention compensates for signal distortions caused by the RF signal path.
