Abstract This article describes a circuit that facilitates the measurement of currents from amps to hundreds of amps with a high degree of precision. Introduction There are many applications that require the measurement of current. Many digital ...
With the trend toward miniaturization, temperature effects in power electronics are more pronounced than ever. If you’re dealing with temperature fluctuations in your circuit, you may need a stabilization system to keep the temperature ...
You sometimes need to measure the differential temperature between two points in a system to a greater accuracy than that required in measuring the absolute temperature at either of the individual points. Differential-temperature measurement is ...
The Ćuk topology is ideal for generating a negative output voltage from a positive supply voltage. Negative voltages are needed in many systems to enable useful readout of signals from certain sensors. For this, a signal chain may need to be ...
Abstract Robust systems often allow multiple power sources. When different power sources are used to power a device, switches need to be implemented to separate the power supplies from each other to avoid damage. This can be accomplished with ...
Even switch-mode power supplies with a fixed switching frequency do not always show a continuing pattern of pulses. In some conditions, pulses are omitted for various reasons. This is important to consider for output ripple voltage and EMI effects. ...
Abstract There is a new product type in the industry, the digital low dropout (LDO) linear regulator. It offers telemetry and adjustability of a linear power supply in a very small footprint. Such solutions are used in ultralow noise applications ...
This article will illustrate how special converters equipped with PassThru mode can be useful when the circuit’s input voltage is too high or too low to power a load. It will give examples of how PassThru mode is used with buck-boost ...
Abstract This article discusses the applications of an operational amplifier for electrochemical gas sensors such as ethanol and carbon monoxide (CO). It also discusses the desired performance to provide optimum results for accurate measurement of ...
Impact of ADC resolution and its reference Engineers always want to get all they can from their circuits; this holds for analog-to-digital converters (ADCs). To maximize performance from an ADC, resolution is perhaps the primary spec to focus on. ...
