proportional to load resistance. For example, the open-loop gain will be 17dB lower with a lkl load than with a 10kl load. If the amplifier is used strictly for DC, this lower gain is of little consequence, since the DC gain is typically greater than 120dB even with a lkl load. However, for wideband applications, the best frequency response will be achieved with a load resistor of 10kl or higher. This will result in a smooth 6dB/octave response from O.1Hz t0 2MHz, with phase shifts of less than 10 degrees in the transition region where the main amplifier takes over from the null amplifier.
