AC constant current source with constant frequency

[catsilly]

Hi, Can anyone give me a circuit for a AC constant current source with a constant frequency as well? I need a 2mA pk to pk while the frequency is set at 1KHZ. Thanks in advance

Thanks! May I ask what op-amp you used?

Vcc=16v
Vce=-16v

0 < Load < 12K (Capacitive, resistive or inductive)

LM358 may be.

ac current from function generator

hi, I'm using a function generator to generate sine waves. However, I need the output of the function generator is in terms of volts. I need a way to convert the voltage into a constant current. Does anyone have any idea on how to accomplish this?
