| Abstract: | A configuration
of voltage mode (VM) multi-function biquad filters (MBF) is presented in this
paper. The configuration (MBF) is implemented by using two OTAs (one dual
output and other single output) and two capacitors. It realises all standard
filtering functions i.e. low pass (LP), high pass (HP), band pass (BP), notch
and all pass (AP). This configuration (MBF) can also be constructed using a
single OTA, two capacitors and one resistor. It employs minimum of active and
passive components and provides an attractive feature in case of BP filter that
it can be designed for high Q. In addition, the circuit enjoy low sensitivity
performance. The experimental results that confirm the validity of the circuit
are included. |
