Abstract :
Equations are supplied for the design of a widely known active filter building block, namely the twin-T single-amplifier building block (TT-SABB), when used as a frequency rejection network in its standard form. Through the proposed equations, the required value of pole and zero frequency and pole Q are realised by assigning free preferred values to the capacitors and then computing the resistor values for minimum gain-sensitivity product.
