Title:
動作状態検出回路
Document Type and Number:
Japanese Patent JP3656758
Kind Code:
B2
Abstract:
A detection circuit comprises a voltage-current conversion circuit (R) supplied with a first voltage signal indicative of the state of an object circuit (13) for producing an output current (I) in response thereto, a detection circuit (11) supplied with a second voltage signal (VC) for detecting the state of the object circuit, and a clamping circuit (12) supplied with the output current of the voltage-current conversion circuit for clamping an output voltage (VB) of the voltage-current conversion circuit and further for producing the second voltage signal in response to the output current of the voltage-current conversion circuit such that the second voltage has a magnitude proportional to the first voltage signal.
