Integrator ramps up/down, holds output level
01.16.2018 · Circuits
Op-amp integrators can ramp to saturation, and a capacitor-discharge switch can reset them. Alternatively, you can input-switch them to ramp up and down in triangle-waveform-generator applications. Much searching through online “cookbook” circuits turned up no means of ramping an op-amp integrator to hold at a preset constant voltage level...

Simple Transient-Response Measurement Determines Power-Supply Bandwidth
01.11.2018 · Articles
It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response – no good reference exists that defines this in simple terms. It seems like a straightforward problem, which should have a simple solution. The higher the bandwidth, the faster the loop responds, and with less voltage deviation...
