ckt to lower output by a constant delta

06/03/2009 3:35 AM

hi, i have a certain voltage output(Vo) that I want to lower by a constant delta to produce Vi. Vi will always be about 200 volt less than Vo:

Vi = Vo - 200

Thanks,

Use an op-amp with voltage dividers to control drop across transistor.
