Principle: Sawyer-Tower measuring system is used in hysteresis measurement which measures data by measuring voltage drop across the sample. The Sawyer-Tower measuring system uses sense capacitor which is replaced with circuit in the virtual ground measurement system. Therefore virtual ground measurement has more accuracy. The virtual ground measurement consists of amplifier and Integrator circuits. The precision DRIVE terminal is connected to the sample and RETURN terminal is connected to transimpedance amplifier with a virtual ground potential. Alternating voltage is applied to the sample through drive terminal results in polarization which leads to charge. The charge flow the sample due to applied DRIVE voltage is collected by the Integrator circuit whose measured output voltage translated to the Vision software. Errors are rejected in the measurement because of DRIVE and RETURN circuit matching with respect to speed and current sinking ability. The advantages of the virtual ground measurement system are; back voltage of sense capacitor is completely avoided and the charge developed by parasitic capacitance is made zero due to its association with RETURN port.
Application: Electric Field vs. Polarization Measurements of bulk samples.
