3: Nodal Analysis

We assume the interconnections have zero resistance so all points within a node have the same voltage. Five nodes: A,···,E. Ohm’s Law: VBD = IR5 KVL: VBD = VB −VD KCL: Total current exiting any closed region is zero.

Lecture 8 - Timing Constraints

Metastability is a problem that arises when an external input NOT synchronised to the system clock is fed into our synchronous circuit. Since the input signal could change anytime relative the the clock edge, metastability will occur. It could also happens when a signal crosses from one clock domain (Clock1) to another clock domain (Clock2).

MT-047: Op Amp Noise - Analog Devices

In bias-compensated input stages and in current feedback op amps, the current noise cannot be calculated. The current noise in the two inputs of a current feedback op amp may be quite different. They may not even have the same 1/f corner. IN+ Figure 3: Input Current Noise . Current noise is only important when it flows in an impedance, and thus ...
