I’ve been spending a lot of time thinking about op amps and comparators lately. One of the common uses of an op amp is as a “unity gain” buffer, meaning that the output voltage is as close as possible to being the same as the input voltage. At a glance this might seem like a […]

Wideband communication systems usually require an ultra-low noise regulator to power the VCOs and PLLs. The regulator must also be able to reject any ripple presented at its input. In a typical system, an ac input is converted to an isolated dc supply rail, –48-V, for example. This rail is then converted to an isolated
