Abstract
This paper presents an alternative circuit configuration for realizing the recently introduced active building block, namely full balanced voltage differencing buffered amplifier (FB-VDBA), eminently suitable for integration in BiCMOS technology. The proposed FB-VDBA consists of a fully differential transconductor as an input stage, and the voltage buffer and inverter as output stages. The circuit has been designed using bipolar and MOS transistors, in order to achieve the advantages of the both technologies. Using single FB-VDBA, one resistor and one capacitor, the voltage-mode all-pass filter is constructed for the specific application of the designed active element. PSPICE simulation results, obtained by using the real transistor parameters of the standard 0.35 μm BiCMOS technology, are performed to confirm the performances of the proposed circuit and its application.
