Various methods for performing amplifier gain compensation to correct for variations in temperature are provided. One example method includes modifying a gain adjustment value based on a current temperature reading, receiving a signal,applying a gain adjustment to the signal based on the gain adjustment value, comparing the gain adjusted signal to a plurality of thresholds to generate respective comparison outputs, and selecting one of the comparison outputs for use in determining content and timing information of the received signal. Related systems and apparatuses are also provided.
