Description 388-396
Frequency-selective filters are usually required at the receiving end of a communication system to change the frequency
range of a band-pass filter (BPF), which is used to extract the broadcast signal. In this study, we have designed such
frequency-selective filters using a novel bulk-driven current differential transconductance amplifier (BDCDTA) as its
fundamental building block. This BDCDTA is first used to create a biquad filter, and the designed filter is then reconfigured
for frequency selection. The proposed frequency-selective filter structures have the capability of providing a constant gain
based on the communication system's requirements. The suggested structures with CMOS 180 nm technology parameters
are validated using PSPICE and the Cadence Virtuoso design environment. The theory is confirmed by pre and post-layout
simulation. PVT corner and Monte-Carlo analysis demonstrate its applicability for a broad range of applications and provide
a range for its use under various conditions. This design is suitable for low voltage and low power applications due to the
bulk-driven transistors, and the suggested structures are designed especially for medium wave communication and
biomedical signal processing.
