Abstract
A method, apparatus and computer program product for a method of operating an analog-to-digital converter of a transceiver which includes a transmitter and a receiver, the receiver including the analog-to-digital converter. The method includes determining a maximum conversion rate of the analog-to-digital converter, wherein the determining step includes determining a temperature of the analog-to-digital converter, and selecting a conversion rate of the analog-to-digital converter, based on the determined maximum conversion rate and a frequency of an unwanted signal component of the receiver, such that the selected conversion rate places an alias response of the unwanted signal component to a frequency range which is substantially non-overlapping with a wanted signal component of the receiver.
Claims18
A method of determining a maximum conversion rate for an analog-to-digital converter of a transceiver, the transceiver comprising a transmitter, a temperature compensation unit and a receiver, the receiver comprising said analog-to-digital converter, the method comprising:
- determining the maximum conversion rate for the analog-to-digital converter from among a plurality of possible maximum conversion rates, wherein the step of determining said maximum conversion rate comprises determining a temperature by the temperature compensation unit and then determining, dependent on the determined temperature, which of the plurality of possible maximum conversion rates will be the determined maximum conversion rate as a function of the temperature;
- and
- selecting a conversion rate for the analog-to-digital converter that is equal to or less than the determined maximum conversion rate based on the determined maximum conversion rate and a frequency of an unwanted signal component of the receiver, such that the selected conversion rate places an alias response of the unwanted signal component to a frequency range which is substantially non-overlapping with a wanted signal component of the receiver.
An apparatus comprising:
- a processing unit,
- at least one memory for storing a computer program, and
- a transceiver coupled to the processing unit, the transceiver comprising a temperature compensation unit, a transmitter and a receiver, the receiver comprising an analog-to-digital converter,
- the at least one memory with the computer program being configured with the processing unit to cause the processing unit to:
- determine a maximum conversion rate for the analog-to-digital converter from among a plurality of possible maximum conversion rates, wherein determining said maximum conversion rate comprises determining a temperature by the temperature compensation unit and then determining, dependent on the determined temperature, which of the plurality of possible maximum conversion rates will be the determined maximum conversion rate as a function of the temperature;
- and
- select a conversion rate for the analog-to-digital converter that is equal to or less than the determined maximum conversion rate based on the determined maximum conversion rate and a frequency of an unwanted signal component of the receiver, such that the selected conversion rate places an alias response of the unwanted signal component to a frequency range which is substantially non-overlapping with a wanted signal component of the receiver.
A non-transitory computer-readable medium embodying instructions that when executed cause a processing unit to perform a method of determining a maximum conversion rate for an analog-to-digital converter of a transceiver, the transceiver comprising a temperature compensation unit, a transmitter, and a receiver, wherein the receiver comprises the analog-to-digital converter, the method comprising:
- determining a maximum conversion rate for the analog-to-digital converter from among a plurality of possible maximum conversion rates, wherein determining said maximum conversion rate comprises determining a temperature by the temperature conversion unit and then determining, dependent on the determined temperature, which of the plurality of possible maximum conversion rates will be the determined maximum conversion rate as a function of the temperature;
- and
- selecting a conversion rate for the analog-to-digital converter that is equal to or less than the determined maximum conversion rate based on the determined maximum conversion rate and a frequency of an unwanted signal component of the receiver, such that the selected conversion rate places an alias response of the unwanted signal component to a frequency range which is substantially non-overlapping with a wanted signal component of the receiver.
