Title:
電圧-周波数変換回路およびそれを備えた血圧測定装置
Document Type and Number:
Japanese Patent JP5326654
Kind Code:
B2
Abstract:
A resistor element is arranged between an input terminal and a node. A switch element is arranged between the node and a ground voltage, and is conducted according to a voltage level of the node. A resistor element is arranged between the nodes. A resistor element is arranged between the node and one side of the input node of an NOR circuit. A capacitor is connected between the nodes. The input node of the NOR circuit is connected to the node through the resistor element and a ground voltage. The input node of an NOR circuit is connected to an output node of the NOR circuit and the ground voltage. The input node of the NOR circuit is connected to the node and the ground voltage.
