摘要： A stacked pre-driver stage and a power amplifier including the stacked pre-driver stage are described. The stacked pre-driver stage comprises stacked pre-drivers arranged in series between a supply voltage and a reference voltage. Each pre-driver includes a pre-driving amplifier, together with MOS transistors. Each pre-driver is subject, in operation, to a voltage difference which is inferior to a maximum allowed use voltage of the MOS transistors with a largely reduced voltage drop across the regulator included in the power amplifier.

摘要： Methods and system for using a multifunctional filter to minimize insertion loss in a multi-mode communications system are described. Specifically described is a multifunctional filter that is configurable to operate in a band-pass mode when a first type of signal is propagated through the multifunctional filter, and to operate in a low-pass mode when a second type of signal is propagated through the multifunctional filter. The multifunctional filter presents a lower insertion loss to the second type of signal when operating in the low-pass mode than in the band-pass mode.

摘要： Methods and apparatuses for use in tuning reactance are described. Open loop and closed loop control for tuning of reactances are also described. Tunable inductors and/or tunable capacitors may be used in filters, resonant circuits, matching networks, and phase shifters. Ability to control inductance and/or capacitance in a circuit leads to flexibility in operation of the circuit, since the circuit may be tuned to operate under a range of different operating frequencies.
