A diode-resistor network for modifying the gain/bandwidth of the feedback loop. The feedback loop gain modifier circuit comprises two (2) diodes and a resistor coupled and parallel with a resistor in the AC feedback path of an amplifier. The diodes are connected such that one diode conducts on a voltage bus overshoot and the other diode conducts on a voltage bus undershoot. In this manner, during large step load transients, one of the gain modifier circuits diodes conducts thereby coupling the resistors in parallel resulting in a modified the gain/bandwidth of the feedback loop. In this way, the feedback gain modifier circuit does not affect the small signal feedback loop stability because it is only activated when a large transient is present.
