Originální abstrakt

This Letter introduces a new circuit topology of the simple electronically controllable voltage-mode bilinear two port (BTP) employing two operational transconductance amplifiers. The proposed two-port circuit is completely resistorless and contains only a grounded capacitor. It has a high-impedance input (a simple cascading of sections is possible) and allows an independent electronic adjusting of zero and pole frequency of the transfer function. The operation of the BTP circuit is demonstrated for two different locations of the pole and zero frequency coordinates. Moreover, a direct application of four BTPs in fractional-order integrators (order −0.11 and −0.33) with phase shifts −10° and −30° is shown. Design specification is verified by experimental measurements.
