Generation of OTA-C filter structures from active RC filter structures

The nodal voltage simulation method has been employed previously to derive new active RC and MOSFET-C filters from well-known active RC filters. This technique is shown here to also be useful for obtaining new OTA-C filters from well-known active RC filters. Specifically, it is shown how OTA-C biquads can be directly generated from active RC filters while retaining their useful properties.<
