摘要：

A Norton op amp and a zenar diode make a simple window comparator with upper and lower thresholds that can vary over a wide range. Current into the op amp's noninverting input varies linearly with the input voltage, while the current into the inverting input changes slope at the zener voltage. The circuit requires just one supply voltage.
