WHAT ARE THE DESIGN RULES FOR ANALOG AND DIGITAL PCB DESIGN?

In this tutorial we are learning about WHAT ARE THE DESIGN RULES FOR ANALOG AND DIGITAL PCB DESIGN? High frequency analogue signals · Keep HF trace lengths as short as possible to reduce emitted radiation & pick up points. · Route HF traces away from sensitive signal lines to avoid cross coupling. Use GND ‘guard’ […]

What is ringing, undershoot and overshoot in PCB Design ?

In this tutorial we are going to learn about What is ringing, undershoot and overshoot in PCB Design ? Ringing is a signal timing related problem & can be defined as the overshoot/undershoot of a signal, a number of times following a logic level transition. Ringing is repeated overshoots & undershoots. It can occur due […]

WHAT ARE THE TWO MODE OF INTERFERENCE ?

In this tutorial we are going to learn about WHAT ARE THE TWO MODE OF INTERFERENCE ? EM disturbances can appear in the form of Common-Mode & Differential-Mode voltage & current components. Differential mode also called symmetrical noise/interference occurs when noise currents travel between live & neutral. The differential mode voltage components are measured between […]

WHICH ARE MAGNETIC COMPONENTS FOR EMI & EMC REDUCTION.

In this tutorial we are going to learn about WHICH ARE MAGNETIC COMPONENTS FOR EMI & EMC REDUCTION. Inductors · Select inductors with a low self capacitance and series resistance. · Use ferrite beads to add inductance to component leads. · Use ferrite beads to damp out parasitic oscillations. · Position inductor close to high […]

WHAT IS CIRCUIT DESIGN TECHNIQUES?

In this tutorial we are going to learn about WHAT IS CIRCUIT DESIGN TECHNIQUES? Use the minimum clock speeds possible for logic circuitry. Select the slowest switching speed logic. Select the logic with the greatest noise margin. Select logic families with the lowest switching energy. Avoid the use of both high impedance inputs and outputs. […]
