Abstract

This brief presents a high-voltage charge pump with pseudo-continuous regulation using dynamic clock voltage scaling. We propose a small-signal model of the charge pump to facilitate co-simulation of the linear amplifier and the capacitive switching converter, and it shows good agreement with the time-domain ac simulation results. A novel lead compensation is proposed in the amplifier using current-mirror Miller compensation, which ensures loop stability without a large load capacitor at the charge pump’s output. The proposed regulated charge pump has been implemented in a 65-nm CMOS process, and the chip area is

基于动态时钟电压缩放的伪连续输出调节高压电荷泵

本文介绍了一种利用动态时钟电压标度实现伪连续调节的高压电荷泵。为了方便线性放大器和电容开关变换器的联合仿真，我们提出了电荷泵的小信号模型，该模型与时域交流仿真结果吻合良好。提出了一种采用电流镜米勒补偿的放大器引线补偿方法，保证了回路的稳定性，而无需在电荷泵输出端使用大的负载电容。所提出的可调电荷泵已在65纳米CMOS工艺中实现，芯片面积为$280~{\mu}$ m ${\times}$ 300~{\mu}$ m。在2.5 V电源下工作，在9.6 V输出时，可在不同负载电流和泵浦频率下保持< 21 mV纹波电压。负载暂态电流为0~ 50~{\mu}$ A，边缘时间为160-ns时，欠冲值为58 mV，恢复时间约为0.8~{\mu}$ s。
