- There's a TR out from Lincoln Labs (TR 824, Floating Gate Circuits in MOSIS,
- J.R. Mann) that describes techniques for doing high-voltage NFETs and PFETs
- in the Mosis low-noise analog process. I have fabbed the circuits from this
- TR and they have worked very well, providing 0-5V input levels, 0-25V output
- levels, with no static current consumption. I have also made bipolar drivers
- in this process, using a floating NPN transistor and a well resistor pullup,
- that worked well at 60V, but of course had considerable static current in
- one state.
