thanks for that

just a thought, but i think you should check it.

it seems to me that the configuration of the amp-op is non-inverting, with gain of 2.
it would give an output of 6,6v, if it had high enough Vdd.

And Q5 is wrong. You should really stick to a diode for that job, 1N4148 are less than a cent each and is probably the most common diode on the planet.

I hve given the replay to this in my blog itself.
cz it comes only 1.8V so we need a gain 2 over there

Q5 willl work and i tested it.
cz it needs only a high speed diode.
but i will also say in4148 is a better option.
