Window comparator |
摘要 |
A family of window comparator circuits are arranged to monitor differential input signals and indicate when the difference between the signals is between two limits. Each of the window comparator circuits includes an input circuit having at least one current source. The input circuit is responsive to a differential input signal for conducting two dependently variable currents through an output circuit. At least one voltage dropping element is connected to each current source in the input circuit for establishing the limits of the window comparator. The output circuit responds to changes in the ratio between the two currents conducted therethrough for indicating that the differential input signal is between the two limits.
