Active Filters Applications
Ex: f
Fine tuning can be further accomplished through R
Miscellaneous Applications
• Since for this filter the GBW product of all 4 amplifiers has been designed to be the same (∼1 MHz) only one current source can be used to bias the circuit.
• For better performance, use a matched NPN pair.
