ABSTRACT:
An amplifier circuit in a wireless telecommunications device includes a digital-to-analog converter (DAC) and a mirror circuit to deliver variable current levels to transmission circuitry. The DAC receives a digital signal indicating the desired current strength under the particular device circumstances and requirements, and an analog signal corresponding thereto is forwarded to the mirror circuit, which amplifies the analog signal to the desired level for driving the transmission circuitry.
