- Marián ŠtofkaIn advanced IC comparators, programmable hysteresis eliminates 0V-centered differential-input-voltage noise and improves the comparator’s response if its differential-input voltage is low or varies slowly over time. For example, the ADCMP609 ...Sep 7, 2022
- Marián ŠtofkaPassive current shunts for measuring the value of current flowing through a relatively small-value resistor often have a full-scale voltage drop of 60 mV for higher-power equipment and 200 mV for electronic instruments. Similarly, simple ...Aug 22, 2022
- Marián ŠtofkaAutozero amplifiers have almost zero drift and input-offset values of 1 to 20 µV. You can compensate for the initial voltage offset of an auto-zero amp in sensitive circuits, such as dc amplifiers and integrators, requiring the processing of ...Aug 17, 2022
- Robert S. VillanucciMeasurement and process control loops often use 8-bit microcontrollers. The devices are inexpensive and widely available, and they can be programmed in many popular high-level languages like C and Basic. However, if the loop requires a nonlinear ...Aug 1, 2022
- Chris ToliverSome voltage references can be used as shunt regulators, either by tying V IN and V OUT together or by leaving V IN open. These devices are limited to low currents, however, with a typical limit of around 10 mA. Standard Zener diodes serve the same ...Jul 25, 2022
- Stephen WoodwardNumerous and evil are the forces of darkness that conspire to frustrate accurate analog-to-digital conversion of wide-dynamic-range analog signals. Among these gremlins lurk common-mode-voltage noise and signal amplitudes too variable to fully use ...Jul 21, 2022
- Jim HagermanLinear Technology's recently introduced LTC4300 chip buffers I 2 C clock and data lines to and from a hot-swappable card. This task is difficult because the IC must work bidirectionally, meaning that you can simultaneously and actively drive ...Jun 30, 2022
- Marián ŠtofkaA previous Design Idea describes an astable multivibrator that gets hysteresis from the positive feedback stage using a technique you can characterize as positive-capacitive feedback ( Reference 1 ). It creates hysteresis by a charge transfer to ...Jun 29, 2022
- Mike IrwinThe circuit in Figure 1 is a variation on the familiar integrator/comparator triangle-wave oscillator, which you typically implement with two op amps. An integrator and a comparator connect in a positive-feedback loop; the comparator drives the ...Jun 21, 2022
- Marián ŠtofkaNonlinear systems often need to become linear to be useful, and the circuit in Figure 1 provides a nonlinear sawtooth pulse for a PWM (pulse-width modulator) that can compensate for nonlinearities in sensors, controllers, or systems. The circuit ...Jun 20, 2022
