- Figure 1 is a “charge pump” type V/F converter specifically designed to run from a 3.3 V rail. A 0 V to 2 V input produces a corresponding 0 kHz to 3 kHz output with linearity inside 0.05%. To understand how the circuit works assume ...26-06-2023
- This article describes an active load circuit that can be used to simulate a battery in any state of charge. The battery simulator provides a constant-voltage load for a battery-charging circuit, independent of applied charging current. The ...22-06-2023
- It is often desirable to determine a battery’s internal resistance to evaluate its condition or suitability for an application. Accurate battery resistance determination is complicated by inherent capacitive terms which corrupt results taken ...22-06-2023
- 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 ...31-05-2023
- 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 ...30-05-2023
- 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 ...23-05-2023
- 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 ...19-05-2023
- Figure 1’s circuit achieves a wider dynamic range and higher output frequency than any commercially available voltage to frequency (V-F) converter. Its 100 MHz fullscale output (10% overrange to 110 MHz is provided) is at least ten times ...12-05-2023
- No currently available V-F converter will accept bipolar (AC) inputs. This feature is desirable in power line monitoring and other applications. Figure 1’s V-F converter accepts 10 V inputs, producing a 0 kHz to 10 kHz output. Linearity is ...24-04-2023
- Verifying the rise time limit of wideband test equipment setups is a difficult task. In particular, the “end-to-end” rise time of oscilloscope-probe combinations is often required to assure measurement integrity. Conceptually, a pulse ...21-04-2023
