Abstract
An apparatus includes a first bias circuit configured to generate a first current that varies with temperature according to a first slope. The apparatus also includes a second bias circuit configured to generate a second current that varies with temperature according to a second slope. The apparatus further includes a low noise amplifier including a transconductance stage that is responsive to an output of the first bias circuit. The apparatus also includes a load coupled to an output of the low noise amplifier and responsive to an output of the second bias circuit.
