| AC constant current source|
I am trying to design an AC constant current source (1 mA p-p output) but facing many difficulties. I tried to build it as if it were a DC current source using instrumentation amplifiers(INA121P and OPA277P) (it worked perfectly for DC). As soon as I switch to an AC input voltage the circuit stops behaving as a constant current source. Is there a way I can get my AC current source?

I'm sorry but your question is outside the scope of this help desk. This help desk's goal is to assist people with communication cabling issues.
I found a number of power supply forums by doing an Internet search (I use Yahoo) and type in "Power Supply Forum". I think these groups would be better in answering your question.
