Improving Phase Margin for Highly Reactive Rail-to-Rail Output Stage Impedances in Op Amp and Fully Differential Amplifier Applications
Michael Steffes  
9/7/2018   Post a comment
Modern Rail-to-rail (R-R) output stage op amps, or fully differential amplifiers (FDAs), can sometimes get into a low phase margin condition for relatively simple circuits. Using the phase margin simulation test of Reference 1, a few simple external phase margin improvement methods will be shown. These tests and fixes are best done in simulation prior to board layout. Where the device model for a R-R output device is perhaps not including the higher frequency reactance, places for these tuning elements might be put into the board layout as a hedge against future stability problems.

Current Shunt Resistor Inductance: It Matters
Jerry Steele  
8/16/2018   2 comments
In high frequency switched systems where you measure current with a shunt, you may observe problems such as excessive amplitude on sine wave current ripple, overshoots on square wave ripple or any rapid transition of current, or excessive high-frequency noise. These problems are due to current shunt inductance, which becomes more significant at lower values of shunt resistors

The e-car basic concept is represented by the role of the electronics technology in making the car more comfortable, safe and effectively interacting with the driver. The first characteristic, comfort, is nowadays being dramatically enhanced by the new solution known as Road Noise Control (acronym: RNC) that has been introduced by BOSE during the CES 2019 in Las Vegas
Early microcontrollers had fixed I/O. It may have been possible to connect one of several internal peripherals to the I/O pins, but those pins were restricted and there was never an option of conditioning those outputs
