  1. Ferran Bayes EDN A previous design idea is reminiscent of a similar but somewhat simpler circuit (see [1]). This circuit delivers a rectangular signal with duty cycle varying between 0 and 100% in response to an input signal varying from 0 to 5 V ...

  2. John Guy, Maxim Integrated EDN The increasing acceptance of Class D amplifiers has helped them gain market share from their linear Class AB brethren. That acceptance is no surprise; the advantages of Class D amplifiers are legion, but such ...

  1. Eugene Palatnik EDN Certain measurement applications, such as for pH (acidity) and bio-potentials, require a high-impedance buffer amplifier. Although several semiconductor manufacturers offer amplifier ICs featuring low bias and offset-input ...

  2. The three-amplifier implementation of the state-variable filter in Figure 1 provides for second-order bandpass, highpass, and lowpass responses. The strength of the circuit, however, is in the bandpass response (V OUT /V IN ), in which it's ...

  4. Lawrence Mayes EDN In audio-mixing applications, one frequently required function involves mixing a monaural or single-channel source into a stereo-sound field. Audio engineers refer to a panoramic-potentiometer circuit as a circuit that generates ...

  5. Catherine Chang, Philip Karantzalis and Aaron Schultz, Linear Technology Design Note 564 Our op amp family has expanded with industry-leading speed versus supply current. The LTC6258/LTC6259/LTC6260 family (single, dual, quad) provides 1.3 MHz ...

  6. Horst Koelzow EDN The basis for this Design Idea is a classic two-transistor current source (Figure 1). Current through R 1 depends only on the V BE (base-emitter voltage) of Q 2 and on the value of R 1 itself. The V BE of Q 1 has no impact on the ...

  7. Alfredo del Rio EDN Many flash ADCs, such as Texas Instruments' ADC1175 , have a recommended operating input-voltage range of 0.6 to 2.6 V. However, in some applications, you must convert a symmetrical analog-input signal. The circuit in this ...

  8. Bob Bell EDN Designers of dc/dc switching power converters face the challenge of controlling EMI (electromagnetic-interference) emissions produced during normal operation. If large enough, these emissions conduct through power lines or radiate to ...
