ABSTRACT:
Buffer means are included in the input circuit in a switching comparator. The unavoidable shunt capacitance at the comparison node is thereby isolated from the input terminal. This substantially reduces the comparator d-c input loading to improve comparison accuracy particularly with sources having appreciable internal resistance.
