Abstract

See full text

According to embodiments, an example method for determining an analog-to-digital converter (ADC) output timing in a user equipment may include operating a switch in a first mode to route a system clock from an oscillator to an input of the ADC and determining a first ADC output timing based on a first set of ADC samples generated by the ADC. The method may also include operating the switch in a second mode to route analog signals from a transceiver of the user equipment to the input of the ADC and obtaining a second set of ADC samples generated by the ADC based on the analog signals.
