Title:
VOLTAGE-CURRENT CONVERSION CIRCUIT
Document Type and Number:
Japanese Patent JPS603098
Kind Code:
A
Abstract:
A voltage-to-current converter circuit for outputting a current accurately proportional to the input signal voltage, which converter circuit includes an operational amplifier for providing an output corresponding to a difference between the input signal and a feedback signal, and includes a feedback circuit for detecting the output current in the form of a voltage by making the output current flow through the reference resistor and for feeding back the detected voltage. Further, the feedback circuit includes a polarity inverting circuit which holds the voltage detected by the reference resistor and inverts the polarity of the voltage, and then feeds back to the operational amplifier.
