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. The variable compensation element can include both a variable impedance and negative capacitance, and stability, peaking control, and linearity of the amplifier can be controlled.
