摘要： A method of reducing distortion in the output of an amplifier is provided. The method comprises subtractively combining baseband error signals with the appropriate phase shift with baseband input signals, the baseband error signals generated by subtractively combining delayed fed-forward portions of the baseband input signals with baseband converted portions of a fed-back amplified output signal, the amplified output signal being a distorted replica of combined up-converted baseband input signals. The baseband error signals being filtered prior to the combining function, and also providing inputs to a controller which adjusts active elements of the amplification and fed-back paths in order to minimize the distortion within the output of the amplifier.

摘要： The invention relates to the field of electronics, more particularly to the wire bonds incorporated into an integrated circuit package such as a quad flat pack. a ball grid array or hybrid style module. The present invention takes the normally undesirable wire bond inductance and uses it in an operational circuit where positive inductance is required. The circuit in which the wire bond inductance is used is located primarily in the integrated circuit die housed in the integrated circuit package, but may also include off-die components. In one example, a wire bond is used as the required series inductance in a discrete circuit impedance inverter which consists of two shunt-to-ground negative inductances and one series positive inductance. One of the negative inductances is located on-die, while the other is located off-die.

摘要： Embodiments of the present invention comprise methods and devices for amplifying a signal by amplifying a first signal and by then amplifying a second signal only if the first signal exceeds a predetermined threshold. The first and second amplified signals are then combined, and the combination is fed back to a signal source and used to control the values of the first and second signal. The combination is further transmitted to a load. In the preferred embodiment, the first amplified signal is transmitted through an impedance inverter before it is combined with the second amplified signal.

The method comprises subtractively combining an error signals with the appropriate phase shift with input signals to be amplified.

摘要： A collector boost circuit is disclosed for providing a first voltage in a first mode of operation to a power amplifier, and another voltage in a second mode of operation to the power amplifier. The collector boost circuit uses an indicator signal derived by an RF detector to switch between the first and the second mode of operation. The another voltage is a boosted voltage greater than the first voltage and is provided when required during peak excursions to prevent amplifier clipping through a boost capacitor. The another voltage is continuous and varies in accordance with the detected peak signal amplitude.
