Abstract
A new principle of voltage amplification that is insensitive to drift and aging effects of the feedback resistors is presented, The effect o f mismatch of these resistors is reduced to a second-order effect whic h results in a total gain error of less than 5 x 10(-6) without the ne ed for any calibration. Moreover, the long-term stability of the whole amplifier is guaranteed by the design when used as a chopper amplifie r.
