Abstract :
Active-ladder filters, at high frequencies, require doubleintegrator building-blocks meeting certain stringent requirements, which are not completely satisfied by most of the existing active-compensated double-integrator units. These restrictions are discussed here, and a highquality circuit is pointed out, having all the necessary properties.
