1. Add noise measurements to your benchtop tools
   Measurement Texas Instruments OPA211 OPA376
   The biggest problem with precision noise measurement is that the noise floor you’re trying to evaluate is frequently below the sensitivity of your measuring instruments. The dominant technique for gaging precision op-amp noise is to calculate ...

2. Capacitor-powered electronics is at the core of green design
   Supply Texas Instruments LMC6442
   The concept of using supercapacitors (also known as ultracapacitors, supercaps, etc.), and replacing the batteries in portable micropower applications ( Ref. 1 ) is gaining momentum. In fact, it has become one of the more noticeable technical ...

3. Quartz oscillator with shock excitation
   Oscillators Texas Instruments CD54HC14
   The circuit in Figure 1 seems utterly simple but demonstrates unusual behavior. It produces an almost square wave of odd-integer quartz harmonics, including its main frequency. Figure 1. A simple circuit that produces an almost square wave ...

4. New slope compensation method stabilizes switchers
   Supply Texas Instruments UCC3802
   In switch-mode power converters, peak current control is very popular because of its inherent current limitation and ease of control. However, if the duty cycle is higher than 50%, there is an instability problem. Some background: The up-slope of ...

5. Correct voltage drop and phase shift in transmission lines
   Analogue Design Texas Instruments THS4551
   Many precision test-and-measurement and high-speed analog applications require an exact targeted voltage to be delivered to the device under test or intended load to accurately analyze the device. Design and test engineers are well-aware that this ...

6. Minimizing passive PWM ripple filter output impedance: How low can you go?
   Signal Processing, Filters Texas Instruments TLV2374 TMUX4053
   Simplicity and low cost sustain the popularity of passive PWM DAC ripple filters despite their limitations. One of these limitations is a high output impedance caused by the series sum of filter resistance(s) (R F in Figure 1, one resistor for each ...

7. My favorite design idea of all time…
   Analogue Design Texas Instruments LM318
   The editors of EDN will tell you that the Design Ideas section is the most popular section of the website, this goes back to the print editions, where that was the first section that most if not all readers turned to first upon getting a new issue. ...

8. Squeeze extra resolution from an 8-bit DAC with Shannon decoder idea
   Signal Processing, Filters Texas Instruments TLV2371 TLV5624
   When someone notices that two 8-bit DACs can be bought for less than one 16-bit DAC, a classic question is often asked: Why can’t you simply take two 8-bit DACs, assign one to the MSByte, the other to the LSByte, sum their outputs in a 28:1 ...

9. A safe adjustable regulator
   Supply Texas Instruments LM350
   Figure 1 shows a typical using of LM350 ( LM317 ) adjustable regulator when you need to adjust its output voltage. Figure 1. This voltage is approximately given here as: The potentiometer R2 is often the most unreliable part of the circuit. As ...

10. Two wires carry power and data
    Interfaces Supply Texas Instruments COP888xG/CS LMC7211 LMV7239 LP2952 LP3990
    At times, designers face a limited amount of wire and/or a limited cost to communicate with a remote device such as a sensor. Many devices allow communication over an ac or dc power line employing an AM or FM modulation scheme. However, they tend ...
