• 論文の詳細を見る

• In this paper a new MOS charge pump architecture is presented, where a clock generator is used in each pump stage of the charge pump circuit to elevate voltage exponentially with stages. This charge pump with a clock level shifter is designed to run at an optimized operation frequency, which can make an excellent compromise between the rise time and the dynamic power dissipation. With less stages than the linear-cascade circuit, the power dissipation and the area of the novel charge pump circuit are markedly decreased. The simulating comparison results based on 1.2μm CMOS, p-substrate double-poly double-metal process parameters show that the nonlinear charge pump with a high pumping efficiency can supply a steady 1 mA, 16 v output for portable LCDs.
