charge pump

Figure 1 shows the general form of a charge pump integer divide phase locked loop (a very common topology used for frequency synthesis).

The ADM8845 charge pump is designed for driving up to six white LEDs in parallel while ensuring uniform brightness of a backlit LCD display.

The PLL includes a phase frequency detector, a charge pump, a low pass filter, a voltage controlled oscillator and a frequency divider .

The system utilizes charge pump elevator to enhance the voltage of storage capacitor and effectively increase the reserved energy.

The commutated power of charge pump type was put forward, combined with the technical control demands of electromagnetic forming machine.

The controller is configured to pressurize the reaction chamber to a first pressure through operation of the charge pump.

The charge pump and amplifiers can be placed in a power down mode, consuming less than 1mA of current.

The nonideal factor of the phase-frequency detector and charge pump in phase-locked loop and its overcome method is proposed.

The system also includes a check valve disposed between the charge pump and the reaction chamber.

The check valve is operable to inhibit the flow of fluid from the reaction chamber toward the charge pump.

Charge Pump circuits are used to generate higher voltages from low voltage inputs, using capacitors as storage elements.

It is the basis of computing the size of switch transistors to derive the model of the power dissipation and efficiency of charge pump.

Finally, employing the equivalent electricity quantity approach, the steady state output voltage expression of charge pump is derived.

In this dissertation, theory, model, design and implementation of charge pump phase locked loop frequency synthesizer are lucubrated.

To configure an EEPROM chip, an electric field produced by the charge pump is applied locally to cells marked for modification.

The A8435 high efficiency charge pump IC offer a simple, low-cost white LED driver solution for portable electronics display applications.

When the PFD does not generate pulses in lock mode, the charge pump does not provide charge to the loop filter.

An improved charge-averaging charge pump and the corresponding circuit implementation are presented.

A controller is configured to control operation of the charge pump and the pressure intensifier.

The charge pump is operable to convey a fluid from a fluid source toward the reaction chamber.

The charge pump has been successfully applied to a TFT-LCD driver IC.

A charge pump can be coupled to the loop to balance the current in the series circuit.

A buffer with Miller compensation and feed-forward path for charge pump of TFT-LCD driver IC was designed.

A new automatic amplitude control circuit for VCO, charge-pump AAC, is presented in this paper.

The axial piston pump should have a inlet port on it for external supply of charge pump oil.

A charge pump circuit and method thereof are provided.
