  • Abstract
    A new 3-amplifier biquad of the 2-integrator-loop type is introduced. Like the Akerberg-Mossberg circuit, the new circuit exhibits extremely stable Q-factor if the amplifiers have good matching and tracking properties. In addition, the new circuit provides simultaneous realisation of the three basic filtering functions, and hence is suitable for use as a universal filtering module.
