  • Switching between lower and higher power modes in an ADC for lower/higher precision operations
    Publication number: 20070252745
    Abstract: An analog-to-digital converter (ADC) disposed in a data reception path to convert data from an analog format to a digital format is switched between two or more power modes to conserve power when data is not being received. ADC stays in a lower power-lower precision mode until an inbound data is detected, at which time the ADC switches to a higher power-higher precision mode to convert the data. Once data conversion is completed, the ADC switches back to the lower power-lower precision mode to conserve power.

  • Powering down of DAC and ADC for receive/transmit modes of operation in a wireless device
    Publication number: 20060007030
    Abstract: A digital-to-analog converter (DAC) disposed in a data transmission path to convert data from a digital format to an analog format to be transmitted is powered down during a receive mode of operation for a wireless communication device. Likewise, an analog-to-digital converter (ADC) disposed in a data reception path to convert received data from an analog format to a digital format is powered down during a transmit mode of operation.
