摘要： Known types of amplifiers include so-called class D amplifiers, which first use a pulse-width modulator to convert an analogue signal into a pulse-width modulated switching signal, which is then amplified and subsequently converted back into a continuously variable voltage via a filter. This type of amplifier is particularly energy-efficient and is therefore preferably used for high-power amplifiers. The invention relates to an amplifier device 1 comprising a control device (5), wherein the control device (5) has an input interface for an audio signal (2), and comprising an amplifier unit (9) for amplifying the audio signal (2, 8) downstream of the control device (5), wherein the control device (5) has a delay module (6) that is designed to transmit the audio signal (2), delayed by a delay value delta_t, to the amplifier unit (9) and to automatically and/or autonomously reduce the delay value delta_t from a starting value delta_t to a final value during an adaptation phase AP.

摘要： A transmitter architecture having a single signal path or hardware to cover WCDMA/EDGE/GSM applications, and requires no SAW at the transmitter outputs. The transmitter architecture allows for a transmit convergence feature. A passive mixer with unique driver and furthermore using native devices available from the CMOS process for the mixer cores enables low voltage and low power design, low output noise and high linearity. A digital variable gain amplifier has the capability to cover wide output dynamic range operated from low supply voltage and interfaced digitally with the baseband circuit without DAC. A single transformer is used to combine the outputs from the WCDMA/EDGE and GSM drivers and subsequently convert the differential signal paths into a single-ended signal. RF switches are used to divert the output from the transformer to different bands and applications.

摘要： An amplifier with multiple stages and having improved reliability is described. The multiple amplifier stages are coupled in parallel and include at least one switchable amplifier stage. Each switchable amplifier stage may be operated in an on state or an off state and includes a gain transistor and a cascode transistor. The gain transistor amplifies an input signal and provides an amplified signal in the on state and is disabled in the off state. The cascode transistor buffers the amplified signal and provides an output signal in the on state and is disabled based on an off voltage in the off state. The off voltage may be greater than zero volts or may have one of multiple possible values. The off voltage may be generated based on an output signal level, e.g., may be set to different values for different ranges of output signal level.

摘要： A low noise amplifier (LNA) system with controllable linearity and noise figure versus power consumption is provided. The system comprises two control inputs for tuning. One input controls an effective transistor width, and the other input controls bias current. Changes to the effective transistor width alter a gain that is applied to a signal, and changes to the bias current alter a power consumption of the system. For more stringent signal specifications, an impedance matched inductive degeneration variation of the LNA is provided.

摘要： A number of identical non-uniformly distributed ultra-wideband power amplifier string building blocks are coupled together to form an ultra-wide bandwidth high-power amplifier. The non-uniform distribution results in an amplifier utilizing modular string building blocks that have input and output impedances with only real values. This permits the strings to be replicated and connected together with simple impedance matching. The internal impedance matching associated with the non-linear distribution also absorbs parasitic capacitance to permit the ultra-broadband operation. In one embodiment identical transistors are used for each cell so that the strings may be identically replicated. This permits modular re-use without reconfiguration. In one embodiment a non-uniform distributed power amplifier built using the subject building blocks provides an ultra-wideband multi-octave device suitable for electronic warfare and communications applications, especially to replace traveling wave tubes.
