Abstract

Circuits and methods related to power amplifiers. Power density matching circuits can be provided to match power densities in reference devices and amplifying devices. In some implementations, a power density matching circuit includes a temperature independent current translator with a first transistor and a third transistor coupled emitter to collector between a power supply node and ground and a second transistor and a fourth transistor coupled emitter to collector between the power supply node and ground. The transistors of the current translator can be sized relative to one another to set a current density in the amplifying transistor relative to a current density in the reference transistor. The current translation can provide power density matching between the amplifying transistor and the reference transistor.
