A reduction in reactance is effective because of increases in capacitor reactance at low frequencies and 1/f noise dependence on signal source resistance which result in output noise worsening. : Input bias resistor · Biases the input pin to zero. · Effects VN stability (refer to NF circuit). · Due to differential input, input resistance is more or less determined by this resistance value. : NFB circuit (AC NF circuit).
