Abstract: Amplifiers with temperature-adaptive gain and peaking gain control are described. In one example, a temperature-adaptive amplifier includes an amplifier, a temperature sense circuit, and a peaking control level shifter to bias shift the output of the amplifier and adjust a peaking gain of the amplifier based on the temperature control signal. The peaking control level shifter can adjust a peaking gain of the amplifier based on the temperature control signal. The temperature-adaptive control can help to compensate for peaking gain in amplifiers based on the operating temperature of the amplifier. The control can help to compensate for unwanted changes in amplifier peaking gain, over time, resulting in more consistent peaking gain over the full operating frequency range of amplifiers.

Abstract: Aspects of temperature dependent stabilization and peaking control in amplifiers are described. An example amplifier includes a variable gain amplifier, a power amplifier, a variable compensation element coupled to the variable gain amplifier, and a controller that directs operation of the variable compensation element to adjust one or more operating characteristics of the amplifier. In one aspect, the variable compensation element comprises a variable impedance, and the controller varies the impedance across inputs of the variable gain amplifier based on temperature to stabilize the amplifier. In another aspect, the variable compensation element comprises a negative capacitance, and the controller varies a coupling of the negative capacitance across inputs of the variable gain amplifier based on temperature to linearize gain of the amplifier.
