Stability and Performance Improvement with Feedback in VRM Transconductance Error Amplifiers – A Case Study using the Sandler State Space Average VRM Model

The voltage regulator module (VRM) is the foundation of power integrity. Due to their wide bandwidth and low cost, most newer VRM controllers employ transconductance feedback amplifiers, with the VRM manufacturers recommending a shunt compensation for the error amplifier design. However, most VRM designers and power integrity engineers may not be aware that they have […]

An Analysis on the Effectiveness of 2 and 3 Terminal Capacitors in PDN Design

While 3-terminal capacitors have been widely used in PDN design (attributed to their low ESL), the effectiveness of 3-terminal capacitors has not been fully verified. As they are more expensive than regular 2-terminal capacitors, it is important to understand their effectiveness. This presentation will explain an accurate characterization method to extract ESL of decoupling capacitors and why the ESL values listed in the data sheet are meaningless.  Based on the characterization results, the possibility/effectiveness of replacing 3-terminal capacitors with 2-terminal capacitors (which can greatly reduce cost) is discussed and experimentally validated.
