  1. The Sallen-Key realization of a 5.25-MHz, three-pole Butterworth filter has a gain of 2 V/V and can drive 75 Ω back-terminated coax with an overall gain of 1 (Figure 1). Used to reconstruct component-video (Y, Pb, Pr) and RGB signals, this ...

  2. A few years ago, I worked at a disk-drive company. We had a plating facility that required square waves to drive the high-voltage plating operation. The challenge was that the square wave's pulse width had to be variable, along with the duty ...

  4. Circuits Supply NXP MC68HC908QT1
    Rechargeable nickel-cadmium (NiCd) batteries are widely used in consumer electronics because of their high energy density, long life, and low self-discharge rate. Standard NiCd cells can be charged at different rates: a fast charge with high ...

  1. Circuits Measurement Diodes DMMT3906W MMBT3904 MMBT3906
    You can achieve accurate resistance-temperature-detector sensor measurements without having to resort to using a precision current source. Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision ...

  2. Figure 1a shows the classic implementation of an integrator. The circuit has two properties that may be undesirable in same applications: It necessarily inverts, and it requires a split-supply or midsupply reference. Figure 1b shows an ...

  3. A “swamp cooler” is an easy way to obtain effective air conditioning, especially in hot and dry climates, if a water source is readily available. Although most units are very reliable, the storage-reservoir control usually uses a single ...

  4. The availability of a seemingly limitless variety of monolithic DAC chips makes it easy to implement most digital-to-analog-conversion applications with a single off-the-shelf device. Sometimes, an unusual set of requirements necessitates a ...

  5. Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a single op amp and a power MOSFET, as shown in ...

  6. Figure 1 shows a flyback power supply that has low noise and uses a simple CMOS CD4093 IC for its control. The electrical noise of a converter arises mainly when current switches on. Diode recovery and charging parasitic capacitances create high ...
