Describes a broadband amplifier circuit thoroughly treated by a CAD method. The parasitic elements of all passive and active components including coupling and blocking capacitors were taken into account. Transmission lines were used instead of lumped elements to obtain the desired frequency response. A good agreement between the values of the transfer characteristic predicted and that measured is stated.
