  1. Electronic Design By adding a resistive divider and dc voltage to a standard dc-dc regulator, you can easily develop dc rails below 1 V, all the way down to just a few hundred millivolts. You can generate a tiny dc supply voltage of a just a few ...

  2. Electronic Design Proper component selection can help reduce startup time for gated oscillators. Gated oscillators always present the typical problem of having a delay when a digital input control signal enables its oscillation. This delay happens ...

  2. EDN The superbal circuit will be familiar to anyone involved in balanced signal transmission [1,2]; it is a differential amplifier which presents identical input impedances to both legs of a balanced line. Balanced loading is a necessity for the ...

  3. Abstract Measuring the signals from extremely high impedance sensors is a difficult task. These sensors can have output impedances in the Teraohms (1×10 12 Ω). The tiny signal currents coming from sensors such as Faraday cups and ...

  4. Paul Rako Electronic Design You can’t leave unused inputs floating, but you might not want to connect them to a power or ground rail either. Digital engineers learned long ago that they should not leave unused inputs unconnected. CMOS chip ...

  5. Thomas Weiss, Nexperia In 1969 the first device housed in the breakthrough SOT23 plastic surface mount package rolled off the assembly line. Last year Nexperia alone shipped over 30 billion SOT23 packaged devices. These two facts highlight a key ...

  6. By Michael O'Loughlin EDN In certain applications, design requirements may call upon a system's switched-mode power supply to more promptly deliver its output than would the garden-variety power supply. Figure 1 shows such a supply's ...

  7. By Steve Hageman EDN Many pc-board assemblies require shields to reduce susceptibility to interference from electromagnetic fields. A classic example is a radio receiver, in which the front end usually needs high isolation from the tuning ...
