Designing Interdigital Filter

There are many distributed line topology that can be used to design a filter. One of these is the Interdigital topology. The interdigital utilizes multiple cascading coupled lines arranged in such a way that the termination of each stub (or called resonator) is alternate between short and open circuit. As one of the planar transmission …

The Importance of Software Tools in Education

The study of electrical and electronics engineering has always been a race against time. Ask many of the students studying this discipline, they will comment that it has always been a race against time. A Race against Time Generally, there are a lot of ground to cover in one semester, which means students will not …

Packaging Inductor With Self Resonance Using EDS

What is self resonance? Have you ever wonder why a lumped prototype performance does not match to the simulated one at certain frequencies? This is due to the effect of the parasitic capacitance/inductance resonating with the ideal inductance/capacitance in a lumped element package. Take an inductor for example, at its resonant frequency, the inductor will …
