摘要： A transimpedance regulator may include a switched capacitor converter, with a current input and a regulated voltage output. A DC-DC switching converter with an inductive component may be used as a current source for the switched capacitor converter. In some embodiments the DC-DC switching converter with an inductive component may be operated in a manner expected to provide optimum power efficiency, with the switching capacitor converter providing a desired regulated voltage output.

摘要： Systems and methods for switched-mode amplifiers having improved harmonic distortion are disclosed. High order in-band filtering is enabled without undue trade-off of distortion due to intermodulation/aliasing. A pre-modulation block is introduced, deployed between a loop filter block and a pulse-width modulation block, performing uniform pulse-width modulation. The pre-modulation block attenuates/removes amplitude dependent high frequency ripples before pulse-width modulation. The pre-modulation block in conjunction with the pulse-width modulation block performs double sampling of the input signals.

摘要： A DC-DC switching converter with an LC output filter has a switched capacitor converter providing the capacitance of the output filter. The switched capacitor converter may be a multi-phase switched capacitor converter. Topology of connections between capacitors of the multi-phase switched capacitor converter may be dependent on phases of clock signal(s) provided to the multi-phase switched capacitor converter. The switched capacitor converter may rely on parasitic inductances, or include discrete inductors, in series between connected capacitors to allow for adiabatic or near adiabatic voltage conversion.

摘要： A power stage output node stabilizer may be used to reduce ringing of a power stage output node of a switching DC-DC power converter. The power stage output node stabilizer may be a network of resistors and switches coupling the power stage output node to a higher voltage level and a lower voltage level.

摘要： Present invention is an apparatus and method for power conversion charge pumps that uses cross-coupling capacitors. High efficiency power converter charge pump for both divide by 3 (1/3), divide by 3/2 (2/3) are explicitly discussed. The power conversion charge pumps utilizing cross coupled capacitors may provide up to 40% reduction in a number of switches required for a charge pump implementation, thus reducing design area cost while also resulting in high-efficiency performance.

摘要： A circuit and a method are provided for suppressing the pop and click noise during the power on and power off of Class D amplifiers. The technique also suppresses pops and clicks when the Class D amplifier enters or exits standby mode. A duplicate feedback network is used to establish the stable operating points, including offsets in the Class D circuit without turning on the outputs. The technique works by gradually propagating or dissipating the offset through the signal path of a Class D amplifier by swapping the differential outputs using switches to suppress pops and clicks when starting up and shutting down the amplifier.

摘要： A voltage regulator utilizes a non-invasive sensing capacitor in differentially sensing a current indicative of current of an output capacitor of the voltage regulator. Some embodiments utilize current mirrors and an inverter for determining if the current indicative of current of the output capacitor is above or below a particular magnitude. Some embodiments utilize information indicative of output capacitor current in determining duty cycle for a switching voltage regulator, and some embodiments utilize the information in activating transient control circuitry.
