摘要： The present invention relates to estimating a battery current supplied from a battery to a switching power supply, which provides a regulated output signal to a load, based on a switching power supply current in the switching power supply, and then controlling the regulated output signal to limit the battery current to within an acceptable threshold. The switching power supply current may be provided by one or more switching elements in the switching power supply. The switching elements may be mirrored to provide a mirrored switching power supply current, which is used to estimate the battery current. The estimated battery current may include an estimated average battery current, an estimated instantaneous battery current, or both.

摘要： Embodiments of the present disclosure relate to radio frequency (RF) transmitter circuitry, which includes non-inverting path power amplifier (PA) circuitry, inverting path PA circuitry, and RF transformer circuitry. The non-inverting path PA circuitry provides a non-inverting RF signal and a first power supply (PS) signal to the RF transformer circuitry, such that the first PS signal has a first ripple voltage. The inverting path PA circuitry provides an inverting RF signal and a second PS signal to the RF transformer circuitry, such that the second PS signal has a second ripple voltage. The RF transformer circuitry additively combines the non-inverting RF signal and the inverting RF signal to provide an RF output signal, such that effects of the first ripple voltage and the second ripple voltage are substantially cancelled from the RF output signal.
