Paper title: SIMPLE BICMOS REALIZATION OF FULL BALANCED VOLTAGE DIFFERENCING BUFFERED AMPLIFIER
Author(s): WORAPONG TANGSRIRAT,
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.
