Kerwin Huelsman Newcomb Filter Using Inverting CCII
Ahmed M. Soliman
A voltage mode Kerwin-Huelsman-Newcomb filter (KHN) using the Inverting CCII (ICCII) is given. The filter has high input impedance, employs two grounded capacitors, six grounded resistors and has independent control on Q and on the gain. A current mode KHN filter is generated from the voltage mode circuit. The current mode circuit has very low input impedance; employs grounded capacitors, grounded resistors and has independent control on Q and on the gain. Spice simulation result is included to demonstrate the practicality of the KHN circuit.
