... The constant-current source is based on an LM317 regulator, which can easily provide 48.8 mA. Thus, you can run the op amp at unity gain, which simplifies selection of the resistance values of RA, RB, RC, and RD. For unity gain, all resistors should be equal. Their values should be considerably high ...
