摘要： A circuit and method is disclosed that dithers a switching frequency of a DC-to-DC converter which gets modulated onto an RF carrier such that switching noise is spread over a given bandwidth that is wider than a communications measurements bandwidth. The circuit includes a switching circuitry adapted to transfer energy from a source to a load using a switching signal having a series of switching cycles and a switching frequency. Also included is a control circuitry adapted to generate a pseudo-random value near a beginning of each of the series of switching cycles to determine a maximum switching frequency value based upon the pseudo-random value. The method includes adjusting the switching frequency of the switching signal incrementally from a fixed minimum switching frequency value to the maximum frequency value and vice versa as a function of time during each of the series of switching cycles of the switching circuit.

摘要： A first programmable frequency oscillator, which includes a first ramp comparator and programmable signal generation circuitry is disclosed. The programmable signal generation circuitry provides a ramping signal, which has a first frequency, based on a desired first frequency. The first ramp comparator receives the ramping signal and provides a first ramp comparator output signal based on the ramping signal. The first ramp comparator output signal is fed back to the programmable signal generation circuitry, such that the ramping signal is based on the desired first frequency and the first ramp comparator output signal. However, the first ramp comparator has a first propagation delay, which introduces a frequency error into the programmable frequency oscillator. Therefore, the first frequency is not proportional to one or more slopes of the ramping signal. As a result, the programmable signal generation circuitry compensates for the frequency error based on the desired first frequency.

摘要： The present invention is a switching power supply that switches (dithers) between at least two switching frequencies without introducing a ripple signal at the dithering frequency, which is based on the time duration of a dithering cycle. In one embodiment of the present invention, an average current in an energy transfer element, such as an inductive element, during operation using one switching frequency is regulated to be approximately equal to the average current during operation using any other switching frequency. The average current may be regulated by controlling the durations of transition periods between operating using one switching frequency and operating using another switching frequency. By maintaining a constant average current while operating using different switching frequencies, dithering frequency ripple may be significantly reduced or eliminated.

摘要： The present invention is ripple cancellation circuitry used with a switching power supply, which provides direct current (DC) power via a DC power amplifier (PA) signal to an RF PA final stage. The DC PA signal includes a DC component and a power supply ripple component, which is generated as a result of the switching characteristics of the switching power supply and creates an output ripple in an RF output signal from the PA final stage. The ripple cancellation circuitry substantially cancels the output ripple by adding a ripple cancellation signal having a ripple component that is phase-shifted approximately 180 degrees from the output ripple to the RF output signal. The ripple cancellation circuitry uses a switching signal that is provided by the switching power supply to generate the ripple cancellation signal.

摘要： Disclosed is a power management system for a portable phone, for example, a cellular phone operating according to a specific mobile communications standard GSM. The power management system comprises a switching module which switches automatically from a voltage provided by a battery to a voltage provided by an external power supply when the power management system is connected to an external power supply. Furthermore, the system comprises a module of voltage regulators, each regulator providing a preset voltage, and a first and second voltage converter. The first voltage converter transforms a first input voltage having a first value to an internal voltage having a lower value. The second voltage converter transforms a second input voltage having a second value to an internal voltage having a higher value. An included reset circuit provides an automated reset function. A logic array module is connected to input ports and is associated with a communications interface. The logic array module receives signals for controlling the module of voltage regulators and the reset circuit.
