I have made the regulated charge pump of -6V and it will be connected to the PWELL region only. But for the startup case, when we power on the chip we want the charge pump should be 0. I want a switch which works such that output of the switch is 0 when input is 0 and -6V when it is 1.8V. I have made a switch which works in opposite way. In this picture shown below let's say the output of the charge pump is -3.6V. When we give 0 then I get -3.6V and when I give 1.8V then output is 0. I need a transistors in stacked way. CMOS 180nm technology. 1.8V power suppy |

Not sure what you mean. Could we have a circuit, please? |
