Abstract
A front-end module comprises a bias network including a current mirror, a junction temperature sensor, an n-bit analog-to-digital converter, an n-bit current source bank configured to automatically set reference current levels for one or more operating temperature regions, and a power amplifier. The bias network, junction temperature sensor, n-bit analog-to-digital converter, n-bit current source bank, and power amplifier are integrated on a first semiconductor die.
