| Abstract: | An absolute minimum component
voltage-mode (VM) universal filter, employing two each of operational
transconductance amplifiers (OTAs) and capacitors with three inputs and one
output, is presented. The circuit can be transformed into CFA-based RC-filter
involving two each of current feedback amplifiers (CFAs), capacitors and
resistors. OTA-C circuit enjoys electronic tunability of filtering parameters
while its CFA-based RC version offers low output impedance which suits
cascadability. PSPICE simulation and the experimental results of both the
circuits are included. |
