There are many applications for one or two transistors. These can include voltage and current amplification useful for interfacing between other system blocks (perhaps ICs). Described in this series ...

Nothing is worse for a design team than a chip that fails to work in the bringup lab. Electrical problems are historically a major cause of such failures. Power leaks, power-ground DC paths, missing ...

The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...
