Abstract :
A voltage amplifier that is insensitive to drift and aging effects of the feedback resistors is presented. The mismatch of the resistors is reduced to a second-order effect which results in a total gain error of less than 10 ppm without the need for any calibration. Moreover, the long-term stability of the whole amplifier is guaranteed by the design
