Title: Subscriber line state monitoring circuit
Inventor: SUENO MINORU
IPC: H04M3/18
Filed: 1988-02-29
Abstract: PURPOSE:To obtain the accuracy of a comparator in a broad band of an input voltage by comparing output voltages of an output voltage switching circuit increasing the transfer rate of the comparator to an input voltage when an output voltage of a current detection circuit is small and decreasing the rate when large. CONSTITUTION:When an output voltage detected by a current detection circuit 5 is small, an output voltage switching circuit 6 increases the transfer function (2V at input corresponding to, e.g., 10mA), and when the output voltage of the current detection circuit 5 is large, the output voltage switching circuit 6 decreases the transfer function (5V at input corresponding to, e.g., 100mA). The comparator 7 compares the output of the output voltage switching circuit 6 with a threshold value. Thus, the accuracy of the comparator is increased in a wide range of the input voltage by applying the comparison at a voltage of 1.2V even near 6mA.
