Analog filters, transfer function, high-pass, sensitivity, noise.
The realization possibilities of the third-order high-pass transfer functions are discussed. For this purpose, the CR ladder network with only one operational amplifier (OA) is used, what will give low power consumption. The transfer functions are expressed with the cumulants. In this paper, the OA provides the signal feedback and in that case, the transfer function contains poles and null zeroes. The frequency responses and the time responses are presented as well as sensitivity and noise analysis. The obtained results are confirmed with the SPICE simulation.
