  1. Low-power, low-cost ceramic piezoelectric rate gyros are available, but they lack the low-temperature-coefficient characteristics of their quartz counterparts. However, you can use a servo amplifier to remove the dc level shift due to ...

  2. At least two classic ways exist to address applications requiring sampling of a sum of analog voltages. The most common way is to cascade a classic analog adder and a sample-and-hold amplifier. A classic analog adder is an op amp plus at least ...

  1. Various switching regulator circuits exist to provide positive- to-negative conversion. Unfortunately, most controllers cannot sense the negative output directly; they require a positive feedback signal derived from the negative output. This ...

  2. The circuits in Figures 1 and 2 shows a PWM (pulse-width-modulated) ramp generator that you can use in low-cost switch-mode dc/dc power supplies. Its supply voltage can range from 5 to 35 V dc, and you can set the output-ramp amplitude of 0.3 to 1 ...

  3. First and second amplifiers and range switch The schematic is shown in Figure 3. Figure 3. First and second amplifiers and range switch. The switching is arranged so that there are no unused resistors attached to the signal circuit; they are ...

  4. Design a wideband analog multimeter to measure AC voltages and currents from 20 Hz to 1 MHz with a selectable sensitivity from 1 mV to 100 V, while the ammeter has a selectable current sensitivity of 10 mA to 10 A. It may be surprising to offer a ...

  5. RFID tags, circuits that detect a “wake-up” call and return a burst of data, must operate on very low quiescent current for months or years, yet have enough battery power in reserve to answer an incoming call. For smallest size, most ...

  6. With linear regulators, you measure dropout voltage, V IN V OUT , at the minimum input voltage for which the IC sustains regulation. Low dropout means longer battery life, because the load circuit continues to operate while the battery discharges ...

  7. The circuit in Figure 1 allows standard TTL logic levels to safely drive a high-power dc load. The circuit provides for both signal and ground isolation as well as a solid-state circuit breaker. Figure 1. An overcurrent condition in this isolated ...

  8. There are a surprising number of high output voltage applications for LTC’s micropower DC/DC converter family. These applications include electroluminescent panels, specialized sensing tubes and xenon strobes. One of the key features of the ...
