Poor control loop stability results in degraded power supply rejection ratio, transient response, output noise, and, for mixed signal circuits, degraded jitter. Datasheet application examples and reference designs do not often include stability information, and measurements often conclude the stability is poor.
Current density can be an interesting concept. Graphics based on current density can be fascinating. But from a practical standpoint, current density is irrelevant. It is a consequence of other things, not a determinant of them. What follows will explain why. Read on to discover more.
Infineon Technologies AG, is taking the next step towards smallest power supply devices for automotive electronics. As first chipmaker, the company set up a dedicated production process for flip-chip packages that is fully aligned with the high-quality requirements of the automotive market.
Teledyne LeCroy, Inc. furthers its USB4 testing with the announcement of QualiPHY USB4 electrical transmitter (Tx) and receiver (Rx) compliance test software (QPHY-USB4-TX-RX) for its LabMaster 10 Zi-A and WaveMaster/SDA 8 Zi-B oscilloscopes used in conjunction with Anritsu’s Signal Quality Analyzer-R (SQA-R) MP1900A BERT.
It is about EMC precompliance and debugging tests. The paper explanes the basic EMI debugging process for radiated and conducted emissions and describes in which cases one should use an oscilloscope or better a spectrum analyzer. Download the app note to learn more.
DesignCon announced Istvan Novak, Principal Signal and Power Integrity Engineer, Samtec, as the 2020 winner of the engineer of the year award. The engineer of the year award recognizes the best of the best in engineering and product advancements at the chip, board, or system level. Each year, the award winner receives a $1,000 grant or scholarship to present to the educational institution of their choice. Novak has selected to donate to the radio club of the Technical University of Budapest.
