The Study of Measurement Circuit Based on Current Conveyor
Zhao Ke-ping · Electrical Measurement & Instrumentation · 2009
This paper discusses a measurement circuit of small resistance changes based on current mode technology. The circuit is structured with a current conveyor and an operational amplifier. The design reduces the complexity of resistance bridge, output signal is four times as much as traditional bridge’s, and the circuit can apply for multisensors and needs no extra parts. The study implements the improvement on traditional resistance bridge with current conveyor which is made by current mode technique. The circuit has the following merits: simple configuration, high precision, low cost and being used in electric measurement and instruments.
