  1. As shown in Figure 1, this issue had been previously addressed during pre-internet times in EDN of January 18,1990 but a further detailed look at the idea is warranted thirty-four years later. Figure 1. Archival design idea “Resistor isolates ...

  2. It was a no brainer at first. Circa 1985 equipment still in use by telcos, the DUT was a remote-operated twisted-pair telephone cable analyzer. We had extensively reverse-engineered and repaired several of these a couple years ago, the OEM was ...

  1. While choosing an op-amp buffer for a new high-resolution single-supply DAC, a source of negative supply was considered because the buffer op-amp had to provide true zero voltage on its output. For instance, a typical rail-to-rail output op-amp ...

  2. A well known power supply circuit is the capacitance multiplier. It doesn’t regulate, but instead reduces ripple noise while the output tracks at some fraction of the input voltage (Figure 1). Figure 1. Standard “capacitance ...

  3. Boost converters, like other switchers, have traditionally received their control signals from a dedicated circuit. However, a recent trend is to integrate simple switching-power-supply building blocks into generic devices, such as ...

  4. Here are some simple tips for servo systems that may improve productivity and prevent costly downtime. To help engineers and design teams get all the performance possible from servo systems, here are some of the more troublesome servo predicaments ...

  5. Most engineers are familiar with boost converters, which step up the output voltage (V OUT ) to a value that exceeds the input voltage (V IN ). They are also familiar with buck-boost converters and single-ended primary-inductor converter (SEPIC), ...

  6. Synchronous rectifiers are MOSFETs, driven in such a way as to perform a rectifying function. They often take the place of diodes in the output-rectification stage of switching power converters, because of their lower on-state power loss. In power ...

  7. A solar-powered lead-acid battery charger can ensure that the battery remains fully charged over a wide temperature range. The ideal charging circuit compensates for temperature and sunlight variations, including recovery from shading. Solar or ...

  8. A bi-directional current source for a grounded load will always have some complication in its construction. The improved Howland Current Pump as shown in Figure 1 is the most frequent choice for this function. The Howland requires carefully matched ...
