Hi,

I need a cmos voltage level shifter circuit which shifts *exactly* 400 mV on a DC analog signal.

I thought about voltage adder/substractor circuit but they are not applicable because of the resistors.

Does anybody have an idea how to shift exactly 400 mV on-chip?

Thx,
Krivan

Yepp, it is also a good idea. I've already implemented it but I need a circuit from just a couple of transistors which dont occupy a lot of space, like voltage-follower amp.+resistor...
