Newbie level 4
I'm designing a level shifter to convert 0~5v digital voltage to -15~25v. I know a four mos circuit can accomplish it.
1.That circuit must convert 0~5v to 0~25v, then convert it to -15~25v. Does it a circuit convert the voltage directly?
2.I add two mos to decrease the current when the voltage converts. How can I design the W/L of these six mos?
3.Concerned about the rise time and fall time, how to design the nmos/pmos in first 0~5v to 0~25v circuit and second 0~25v to -15~25v circuit?
Please help me! Thanks!
