<p>PROBLEM TO BE SOLVED: To provide a circuit system including a plurality of input sub circuits connected with a common output node.SOLUTION: Respective input sub circuits include a mutual conductance cell. A diode is connected between an output of the mutual conductance cell and a common output node. A feedback circuit is connected between the common output node and a second input of the mutual conductance cell. A voltage follower is connected between the common output node and a reference voltage, and an input is connected with an output of the mutual conductance cell.</p> |
