RC Snubber Design for SMPS Protection

This part II of the RC Snubber topic discusses the systematic and efficient design process and design verification through simulations and laboratory measurements

RC Snubber Design for SMPS Protection

This is the first of two articles devoted to RC snubber design. In Part I, we discuss the fundamentals of inductive switching and the need for circuit protection.

Impedance of the Four Passive Circuit Components: R, L, C, and a PCB Trace

This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace.

Transmission Line Reflections at a Reactive Load

This article discusses the reflections on a transmission line at the capacitive and inductive loads.

Circuit Theory Model of Ringing on a Transmission Line

This article uses a classical circuit-theory model of a series RLC circuit to explain the phenomenon of ringing on a transmission line, or a PCB trace.

Transmission Line Reflections: Bounce Diagram

This article explains the creation of a bounce diagram for a transmission line circuit (see [1] for transmission line reflections).

S-Parameters Tutorial – Part II: EMC Measurements and Testing

This part II of the s-parameter tutorial presents several examples of the s-parameter use in EMC measurements and testing.

S-Parameters Tutorial – Part I: Fundamental Background

This s-parameters tutorial consists of two parts: Part I discusses the fundamental background needed to understand the concept of s-parameters; Part II explains the s-parameters use in EMC measurements and testing

EMI Reduction by Spread-Spectrum Frequency Dithering

This article examines the spread-spectrum frequency dithering technique to reduce the EMI noise from a SMPS.
