    Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require adjustments or selection of some components to set ...

  1. In advanced IC comparators, programmable hysteresis eliminates 0V-centered differential-input-voltage noise and improves the comparator’s response if its differential-input voltage is low or varies slowly over time. For example, the ADCMP609 ...

  2. You can remotely measure temperature using a 4- to 20-mA current loop as long as 4000 feet and a battery-powered, white-light LED driver. You usually configure this equipment to provide a programmable, constant current to an LED from a battery ...

  3. Circuits sometimes need a gain-of-one buffer to lower output impedance and prevent the load from interfering with the previous stage. For an application involving a 1.5-MHz, low-power transmitter and antenna, a BUF634 buffer IC would work, but a ...

    Resonant power supplies are popular because of high efficiency, low noise, and compactness. You can implement a resonant buck or boost converter using a single switch. The regulation of the output in such a converter derives from using a constant ...

  6. Sometimes, the need arises for a short-circuit tester that supplies a low current to the device under test (DUT) and also uses voltages lower than 100 mV to prevent conduction of semiconductors. The circuit in Figure 1 meets these requirements. R 1 ...

  7. Some voltage references can be used as shunt regulators, either by tying V IN and V OUT together or by leaving V IN open. These devices are limited to low currents, however, with a typical limit of around 10 mA. Standard Zener diodes serve the same ...

  8. ADCs need adequate signal-acquisition analog interfaces to perform at their best. The classic general-purpose ADC front end includes multiple channels of differential input, digitally programmable gain, and track-and-hold capability. This Design ...
