1. A method comprising:
for each time instance of a plurality of time instances:
generating a first ramp signal started at the time instance relative to a respective start of a first counter signal;
generating a respective first comparator output signal based on the first ramp signal and a first threshold signal, wherein the respective first comparator output signal is associated with a first state or a second state;
capturing a respective first value of the first ramp signal in response to a transition of the respective first comparator output signal from the first state to the second state; and
determining a respective second counter value of a second counter signal based on the respective first value; and

determining a scaling factor based on the second counter values and the plurality of time instances, wherein each of the first values is associated with the same first counter value of the first counter signal.
