CMOS Charge Pumps Using Cross-Coupled Charge Transfer Switches with Improved Voltage Pumping Gain and Low Gate-Oxide Stress for Low-Voltage Memory Circuits
Summary :
To overcome the problems of the modified Dickson pump like NCP-2, another pump (CCTS-1) where simple voltage doublers are cascaded in series and each of them has cross-coupled configuration is studied in this letter for possible use in low-voltage EEPROMs and DRAMs. Though this concept of cascading doublers has been previously proposed, it is firstly addressed in this letter that CCTS-1 has lower gate-oxide stress, improved voltage pumping gain, and better power efficiency than NCP-2 so that CCTS-1 can be more suitable for multi-stage pump in particular at low VCC. In addition, CCTS-2 is proposed to overcome the degraded body-effect of CCTS-1 without using boosted clocks when the stage number is large.
