  1. Digital-system designs require you to consider many core voltages. Memory operates at 1.8 V, I 2 C and FPGA devices operate at 3.3 V, microcontrollers operate at 5 V, and charge-coupled-device image sensors operate at 9 to 8 V. Clocks for each ...

  2. The circuit in Figure 1 uses the LM358 dual op amp running as a comparator, plus a few other inexpensive components, to make a TTL (transistor- transistor-logic)/CMOS-logic probe. The circuit gets its power from the circuit under test, which lets ...

  3. The circuit in Figure 1 produces a single debounced pulse each time you press S 1 . Moreover, the circuit uses only logic power from the remote pull-up resistor, R 2 . You can use the circuit to detect when a key is pressed in a nonenergized ...

  4. Amplifiers with positive feedback are the bases of signal-grade pulse-forming circuits. This setup ensures a triggerlike operation in which the input signal crosses the input-threshold level; in most cases, the input signal is a voltage signal. The ...

    Today's digital delay lines can process pulses no shorter than their delay times, and that restriction confines the devices to applications in which the duty cycle remains near 50%. A limited range of available delays (2 to 100 nsec per tap) ...

    Luis Brugarolas EDN A clock-recovery architecture can operate with NRZ digital signals, even at low SNRs. A clock-recovery subsystem is based on a PLL comprising a phase comparator, a loop filter, and a voltage-controlled oscillator (VCO). If you ...

  4. by Shyam Tiwari EDN The need for a compact telemetry system poses a challenge for designing a small, light, low-component-count system. Interfacing serial data from the microprocessor is also difficult because most low-cost RF transmitters do not ...

  5. Raju Baddi EDN When designing logic for higher-than-usual supply voltages, such as 24 V, you can use a voltage regulator with a standard logic family and interface it through level shifters. Alternatively, if the logic is not too complex and the ...

  6. Anthony Smith EDN Converting band-limited NRZ (non-return-to-zero) data to a digital format suitable for microprocessors and other digital systems poses problems when a signal's duty cycle or amplitude varies or when its average level ...
