Uncertainty estimations of an evaluation system for a high accuracy and wideband transconductance amplifier

An evaluation system for high accuracy transconductance amplifiers has been developed. The system has a standard ac shunt and inductive voltage divider for precise evaluations. The measurement capabilities of the system are 4.1×10^-6 (k = 2) for in-phase component, 9.1×10^-6 (k = 2) for quadrature component at power frequencies, and 13×10^-6 for inphase component, 45×10^-6 (k = 2) for quadrature component at 3 kHz.
