Abstract
An amplifying device includes a cascode amplifier and a biasing circuit. The cascode amplifier is configured to receive an input signal and to output an amplified output signal corresponding to the input signal. The biasing circuit is configured to bias the cascode amplifier, the biasing circuit including a first current mirror and a second current mirror stacked on the first current mirror. The biasing circuit improves linearity of the cascode amplifier across a wide temperature range.
