Brain regions operate not in isolation but through their interactions with other brain regions. These interactions are often strongly directional — for example, brainstem sensory nuclei typically send ...

Understanding how the spatiotemporal patterns of activity in neural circuits drive behavior represents a fundamental problem in neuroscience. To define causal relationships between activity patterns ...

After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...

Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some or all of the loops are inside the IC. Accessing these loops ...

Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...
