Hi,
How can I buffer the following circuit, without using an op amp? Do I need to buffer it, were it to be fed to e.g. an ADC reference pin?
I tried simulating a BJT NPN one, the common collector version (biased base, two capacitors, and without the capacitors), but I'm not sure why I've been unable to get the 1V in > 1V out.
Tried with a differential pair and common collector output stage and pretty pathetic to see the failed attempts to get anywhere near 1V out, I don't want to design an op amp, nor do I have that level of ability, I would just appreciate hints or suggestions on how to buffer this circuit, thanks.
Is there an issue with using a 1.5V supply and a ~680mV Vbe NPN transistor as a buffer for the below circuit?
