Title :
A class of stable active filters using unity-gain voltage followers
Abstract :
A new class of active filters using a single unity-gain amplifier is introduced and shown to have a gain-sensitivity product and a maximum spread of component values lower than those for the corresponding Sallen and Key circuits by a factor of Q.
