Abstract
An apparatus includes a first amplifier that includes a transistor that is coupled to an input terminal of the first amplifier. The transistor is biased to operate in a first mode based on a first operating point. The apparatus also includes a second amplifier coupled in parallel with the first amplifier. The second amplifier includes a second transistor coupled to an input terminal of the second amplifier. The second transistor is biased to operate in a second mode based on a second operating point that is temperature-dependent.
