In the attached diagram you can see a small votlage source being added to the inputs of the amplifier and comparator. How would you realize such an offset in a real circuit?
I thought about a Vbe multiplier, but those can only have more drop than Vbe, not less. I am replicating this ideal diode controller with discrete parts, so in the real circuit (normal differential amplifier) I solved it by having slightly different voltage dividers for each input, but that makes the offset change with Vcc. What would you use to achive this small offset of inputs?
