摘要： Apparatus and methods are provided to compensate for parasitic inductances and resistance (such as from package bonding wires) that affect current in duty cycle systems, such as low noise amplifiers (LNAs), that have large varying current consumption. A boost circuit supplies current from a supply VBSTDC to compensate for voltage changes due to a package inductance 204 and resistive voltage drops. To accomplish this, a replica circuit (i.e., transistor Q2) is able to source a current from current source 206-1 (which can be a generally constant current source) that is a replica IRPL of the current ICKT sourced by the input circuit (i.e., LNA 108).

摘要： A power-conversion regulator comprising an inductive reactor, an output filter reactor, and a switch for admitting energy to the inductive reactor, additionally comprises computation circuitry responsive to the flux in the inductive reactor, to a reference signal, to an output voltage, and sometimes to an output load current, for computing the quantity of energy that must be supplied to a load and to the output filter reactor to regulate the output voltage or current to a desired relationship with the reference signal during each chopping waveform cycle driving the switch. As the inductive reactor is charged from an input energy source, the computation circuitry predicts whether the energy in the inductive reactor has become adequate for the regulation.

摘要： The present invention provides lossless switching by configuring the output inductor so that the ripple current amplitude at load conditions results in small negative current during switching. The reconfigured output inductor results in increased ripple current amplitude. This increased ripple amplitude may be further controlled using zero ripple steering techniques to eliminate ripple at the output capacitor. A ripple steering technique involves adding a secondary output to the class D amplifier which steers the switching ripple away from the main output thus substantially relieving the main output from a major artifact of prior art Class D amplifiers.
摘要翻译：本发明通过配置输出电感器来提供无损切换，使得负载条件下的纹波电流幅度在切换期间导致小的负电流。重新配置的输出电感导致纹波电流幅度增加。可以使用零纹波转向技术来进一步控制增加的纹波幅度，以消除输出电容器处的纹波。波纹转向技术涉及将二次输出添加到D类放大器中，其将开关纹波转向远离主输出，从而基本上将主输出从现有技术的D类放大器的主要伪影中消除。

摘要： Recently, the use of class - D audio amplifiers has become more and more widespread. In contrast to the generally employed class - AB linear amplification technology, class - D allows for improved efficiency. However, the class - D principle is known for its poor distortion characteristics. According to the present invention a digital amplifier (18) is provided for converting an audio signal to a power output, comprising a ripple suppression circuit (16) for suppressing voltage ripples in a supply voltage supplied to the bridge circuit with (6) at least one pair of switches. The ripple suppression circuit (16) suppresses ripples in the supply voltage supplied to a switch in the bridge circuit (6), which has been found to cause a major part of the distortions in the output signal of the digital amplifier (18).
