Abstract :
Taking advantage of the structural properties of some universal biquads, a low-cost strategy for off-line testing analog filters has been developed. This new strategy consists in provoking pole-zero cancellation during the test mode operation, without eliminating information about parameters which determine the normal circuit operation. Although area overhead could seem high, it can be very small in many applications
