Realization of the Third-Order High-Pass Transfer Function with Real Zeroes

The realization possibilities of the third-order high-pass transfer functions with the real zeroes are discussed. The filter structure consists the CR ladder network with only one operational amplifier (OA), what will give the low sensitivity circuit with the low power consumption. In this paper, the OA provides the signal feedforward and in that case, the transfer function contains real zeroes, both in and out of the origin of complex plane. The frequency responses and the time responses are presented as well as the sensitivity and the noise analysis. The obtained results are confirmed with the SPICE.
