Title:
VOLTAGE-FREQUENCY CONVERSION CIRCUIT AND BLOOD PRESSURE MEASUREMENT APPARATUS PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2010/098202
Kind Code:
A1
Abstract:
A resistor (16) is provided between an input terminal and a node (N0). A switch (15) is provided between the node (N0) and a ground voltage (GND) and closes according to the voltage level of the node (NC). A resistor (13) is provided between the nodes (N0, NA). A resistor (12) is provided between the node (NA) and one side of the input node of an NOR circuit (11A). A capacitor (14) is connected between the nodes (NA, NC). The input node of the NOR circuit (11A) is connected through the resistor (12) between the node (NA) and the ground voltage (GND). The input node of the NOR circuit (11B) is connected to the output node of the NOR circuit (11A) and to the ground voltage (GND). The input node of the NOR circuit (11C) is connected to the node (NC) and the ground voltage (GND).
