    Dear Ron,
    How can I have a high-current buffer for the op-amp in Howland current source?
    I mean that I need a bipolar buffer placed at the output of op-amp.

    PS: I want to make a AC Current Source based on Howland Current Source which be able to put out 1A and ±15V at up to 50Hz-10kHz.

    Are the 1 A and +/-15 V requirements RMS or peak values?
    Is one end of the load connected to the system ground?
    What is the amplitude of the signal source?
