    Noise in electrical circuits is typically the enemy, and any self-respecting circuit should output as little noise as possible. Nevertheless, there are cases where a well-characterized source of noise with no other signal is entirely the desired ...

    In the early days of personal computers, incorporation of one or two (or more) RS-232 serial ports as general purpose I/O adaptors was common practice. Recently, this “vintage” standard has been largely replaced (after all, it is 64 ...

    A variety of analog front-end functions typically assist ADCs to do their jobs. These include instrumentation amplifiers (INA), digitally programmable gain (DPG), and sample and holds (S H). The circuit in Figure 1 is a bit atypical in merging all ...

    Introduction Photovoltaic (PV) modules are popular and affordable sources of renewable energy. Most photovoltaic modules last about 20 years, but thermal stress and moisture ingress, among other causes, can degrade a module’s output power ...

    Analog-to-digital conversion based on the classic combination of a voltage-to-frequency converter (VFC) with a counter has been around for (many) decades, mainly because it has some durable time-proven advantages. VFC digitization is naturally ...
