The ratio between the emitter and collector current can be expressed as the reciprocal of beta plus 1 and directly affects temperature readings. Thus, transistors with larger betas experience negligible error due to beta variation, while transistors with beta less than 1 can have large temperature measurement errors as beta approaches 1. Remote temperature sensors with beta compensation, such as the TMP431, can correct for these errors, and devices without beta compensation but with offset and η-factor correction registers can also compensate for beta variation.
