Input Impedance Extraction and Application for High Speed Amplifiers, Insight #9
The Signal Sped Up

Here, model testing steps will be shown for the VFA then external adjustments to match reported data sheet numbers will be shown
Stability Issues and Resolutions for High Speed Fully Differential Amplifiers (FDAs), Insight #8

The most recent VFA FDAs focus on lower power, precision, solutions more aimed at Successive Approximation Register (SAR) and delta sigma ADC support. Those will be focus in this FDA stability discussion - but the concepts are backward compatible to the earliest VFA FDAs.

Emerging issues and paths to improve the Phase Margin (PM) for VFA stages that have slipped into perhaps an unsuitably low margin condition

Probably no single issue faces more high-speed signal path designers (and supplier support teams) than the risk of instability in higher speed op amps and fully differential amplifiers (FDA).

Some years back, an excellent blog appeared on EDN stepping through common issues and questions surrounding lower speed Voltage Feedback Amplifiers (VFA). A wider discussion of the unique issues that come with higher speed op amps will be the intent here

How can you accurately measure this impedance to give reliable lead-off detection in ECGs?
Fast switching transitions can yield some disadvantages. Interference in the frequency range of the switching transitions between approximately 20 MHz and 200 MHz increases dramatically.
The U-channel format consists of an open frame PSU mounted into a U-shaped aluminum chassis.
The primary difference between the speakers I designed and the micro- and mini-speakers that Eminence makes is that the diaphragm is connected directly to the voice coil as opposed to an Aluminum or cardboard 'former' to which the voice coil was connected
Autonomous driving represents one of the most interesting fields of research in the electronics and automotive sectors. This interest is growing by means of projects like the “Roobopoli” which includes the design and testing of prototype autonomous cars having integrated microcontrollers.
