| Abstract: | Reduction of the power supply voltage for system on chip(SoC) designs has reduced the voltage gain of the charge pump circuit in embedded flash memory(eFlash).The efficiency of the charge pump circuit for low supply voltages is improved by a charge pump circuit based on the dual-path circuit structure.The circuit uses a feedback inverter to enhance the gate voltage of the charge transfer switch(CTS),with a body-controlled circuit to eliminate the CTS body effect,thus reducing the threshold voltage loss.Test... |
