In this video we discuss the details of 1/f or flicker noise.

Understanding slew rate and bandwidths of current sense amplifiers

This video walks through where one can find current sensing in automotive systems, as well as the typical discrete circuits used in such systems.

In this video we discuss several bandwidth related topics, including the slope of the open loop gain curve and the effects of op amp input capacitance.

In this video we discuss units of op amp gain, bode plots and poles and zeroes, and the definition of bandwidth.

In this video we discuss open and closed loop gain, gain bandwidth product, and quiescent current versus bandwidth.

In this training lab we discuss calculations, simulations, and real world measurements that reinforce the concepts from the bandwidth video series.

In this video we discuss the use of non-inverting gain for calculating bandwidth and some of the secondary effects on bandwidth.

In this video we discuss a technique known as the A-B-A swap, as well as an introduction to PCB parasitics and the importance of PCB cleanliness.

Calculating and simulating error in current sensing systems

In this video we go into further detail on the regions of op amp noise and how to convert noise spectral density to RMS noise.

In this video we continue the noise discussion by performing a full noise calculation for a simple amplifier circuit.

In this video we discuss why capacitive loads cause stability issues and present the isolation resistor compensation technique.

Learn how closed loop output impedance affects load stability in current sense amplifiers, and techniques on how to provide control for capacitive loads greater

In this video we discuss the effects of changing the common mode voltage of op amps at both AC and DC.

Learn more about error from common-mode rejection ratio and how to minimize its effects in a current sensing application.
