Dear Reader,
In one application note, to avoide the unstable operation of a comparator in the linear region, it has been suggested that to keep the input impedance low to reduce the stray feedback path.
Moreover it is recommended to keep input impedance below 10k. Now, how do I reduce the input impedance of a comparator to sink more current from my earlier stage, i.e. opamp. Should I put a series resistance? What about inverting and non inverting terminal?
