Abstract
The transfer function zeros of certain low-sensitivity multi-loop negative feedback active networks are restricted to the left half of the S plane. A technique is described here which eliminates this restriction without affecting the low-sensitivity of the poles. The differential property of the network's main operational amplifier is utilized to introduce new terms in the numerator of the transfer function without affecting the denominator sensitivity. Networks capable of realizing second and third-order functions are derived. Some of the resulting networks were used to realize a low-pass non-minimnm-phage delay function and a high-pass filter and experimental results are included.
