Abstract :
The letter presents a technique by means of which stray-insensitive SC highpass ladder filters may be designed without the need for network synthesis. The starting point is a unit-element cascade (i.e. lowpass prototype from which the corresponding highpass filter is obtained by direct frequency transformation.
