Abstract:
A front-end module comprises a low-dropout (LDO) voltage regulator, a reference current generator, a power amplifier, and a voltage reference configured to provide a reference voltage to the LDO voltage regulator and the reference current generator. The LDO voltage regulator, reference current generator, power amplifier, and voltage reference are integrated on a first semiconductor die.
