Use Schmitt trigger to design a 1 kHz square wave oscillator. Assume the Op Amp supply voltages to be +15V, and the maximum bias current of the Op Amp to be 500nA. Assume that the maximum output of the oscillator to be +-14V.
This is what I have solved so far, The bare circuit i have drawn is as below,but what does the 500nA use for?
For R1 and R2 is it true for me to set any value but the same magnitude?
