'IR detectors - low current?'

Hi Debbie,
           I have a design for a radio pir that uses a pm3 battery and
draws 12 uA. You can use a programmable opamp but I found it was more cost
effective to build it out of discreate transistors. bc547 types have high
gain at low current.

Great! 12uA would fit the bill all right. Errm .... I couldn't persuade u to
email a gif, perchance? :))
