摘要： A radio frequency signal (FIG. 2, 205) is sampled and the sample is conveyed to a video detector (220). The detected envelope amplitude is sent to an envelope tracking circuit (280), a comparator (230), and an envelope tracking and gate biasing circuit (240). Based on the instantaneous value of the envelope amplitude, the comparator (230) selects one of the available supply voltages (340) via switch drivers (270). The selected one of the available supply voltages (340) is adjusted by the envelope tracking circuit (280) and the resulting voltage output (282) is supplied to the drains of the power amplifiers (390), thus enabling operation near saturation. As the instantaneous value of the envelope amplitude increases, the comparator (230) selects higher supply voltages (340) which increases the voltage conveyed to the power amplifiers (390), thereby increasing their power output. In order to maintain constant gain performance, the envelope tracking and gate biasing circuit (240) modifies the gate bias inversely with the changes the drain voltage.

摘要： An rf transmitter (319) used with a single cell battery (101) includes a voltage boost circuit (211) integral with a class S amplifier (290). An rf signal to be amplified is separated into its envelope (amplitude) and phase components. The phase component is applied to the input of a power amplifier (260). The envelope is applied to a pulse width modulator (275) which is used to modulate the voltage supplied to the power amplifier (260). The pulse width modulator (275) controls electronic switches (285, 286) which are disposed between the single cell battery (101) and the primary of a step up transformer (211). The secondary of the transformer (211) is coupled to supply voltage to the power amplifier (260). In this manner, the class S amplifier is powered directly from the single cell battery, via a the transformer (211), and power consumption is substantially reduced due to the switching operation of the switches (285, 286).

摘要： A method and apparatus for efficient power amplification of a wideband signal with a correspondingly wide modulation bandwidth includes an envelope detector (220), an multi-stage class S modulator (270), and a power amplifier (260). The multi-stage class S modulator (270) includes multiple stages (480), where each stage includes a pair of switching transistors (430, 440) and a capacitor (450). The capacitor (450) supplies the inrush current requirements of the stage (480) so that filtering at the switching frequency is substantially provided within the stage (480). Multiple stages (480) are included on a single semiconductor substrate resulting in higher switching frequencies, higher modulation bandwidths, and lower external filtering requirements.

摘要： According to the present disclosure, an inrush current limiter comprises an input (190) for connection to a supply voltage, an output (202) for connection to a load, a current limiter circuit (102), a current bypass circuit (106), and a charge status circuit (104). During the initial charging of capacitors, the current limiter circuit (102) senses a large inrush current and limits the current to a predetermined quantity. The current bypass circuit (106) is switched off during the initial charging of the capacitors. When the capacitors are charged to substantially equal the input voltage, the current bypass circuit (106) is switched on to provide a low-resistance path for the supply current to pass through. In addition, the charge status circuit (104) operates to indicate the supply voltage.

摘要： A method and apparatus for efficient power amplification over a wide dynamic range and for a number of modulation formats includes a carrier amplifier (30) and a peaking amplifier (40). The carrier amplifier (30) operates with a bias generated by an envelope amplifier (80) which amplifies the envelope of an input signal as generated by an envelope detector (70). The peaking amplifier (40) operates with a fixed bias. The outputs of the carrier amplifier (30) and the peaking amplifier (40) are combined using an impedance transforming network (50). Envelope amplifier (80) can be turned on for high efficiency low power level operation, or it can be turned off for standard Doherty-type operation.

摘要： A method and apparatus for efficient power amplification of a high dynamic range signal includes an envelope detector (220), a multi-range modulator (270), and a power amplifier (260). The multi-range modulator (270) efficiently amplifies the envelope of the input signal by selecting a power source as a function of the amplitude of the input signal. Multi-range modulator (200) produces a pulsewidth modulated signal with a duty cycle and an amplitude. When the amplitude of the input signal rises above a reference, the duty cycle and the amplitude are modified so as to keep the multi-range modulator in an operating region of high efficiency.
