새로운 저항차-전압 변환 회로 설계

A novel two type resistance-difference to voltage conversion circuits for low cost and high accuracy measurement system are designed. The one-type circuit consists of CCII+ with dual output, three resistors, and an op amp. The other type consists of LOTA with dual output, two resistors, and an op-amp. The main characteristics of the circuit configuration need not resistors and active devices matching. Simulation results show that the resistor -difference to voltage conversion circuits agrees with theoretical equation.
