چکیده
This paper describes two methods for the reduction of the peak input current during the boosting of Dickson charge pumps. One of the methods is implemented in the fully integrated Dickson charge pumps of a high-voltage display driver chip for smart-card applications. Experimental results reveal good correspondence with Spice simulations and show a reduction of the peak input current by a factor of 6 during boosting. Key-Words: Dickson charge pump, high-voltage generator, peak current reduction, sub-pump boosting, variable frequency boosting, bi-stable display driver.

متن کاملHighly efficient integrated rectifier and voltage boosting circuits for energy harvesting applications
This paper presents novel circuit concepts for integrated rectifiers and voltage converting interfaces for energy harvesting micro-generators. In the context of energy harvesting, usually only small voltages are supplied by vibration-driven generators. Therefore, rectification with minimum voltage losses and low reverse currents is an important issue. This is realized by novel integrated rectif...

pump boosting circuit, one PLL with a charge pump boosting circuit and another one without a boosting circuit (the same as the conventional PLL) have been implemented in a 0 . 8 ~ CMOS technology. Fig. 3 shows the maximum frequency to which both PLLs can lock with a supply voltage change. The proposed PLL can be locked to 672MHz at 3.3V supply, which is 1.9 times the maximum frequency of the co...
متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
متن کاملHigh Speed Delay-Locked Loop for Multiple Clock Phase Generation
In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...
