on either input can reduce stability. In most high resistance applications, a few picofarads of capacitance across the feedback resistor will im-
prove stability.
Low resistances are preferred for low noise applications as a 1k
resistor has 4nV/
√
Hz of thermal noise. Total resistances of greater than
