If you need a very pure sine wave in the audio range, the circuit in Figure 1 can help. It is a simple deal: A sine wave with a THD of 1% coming from a function generator that goes through a trackable low-pass filter, which attenuates the ...
When current pulses with a stable I HIGH /I LOW ratio modulate a semiconductor junction, the ensuing voltage difference (for example, ΔV BE for a bipolar transistor) is a linear function of the absolute (Kelvin) temperature, T. You can use ...
Nearly four decades ago (in his Designs for High Performance Voltage-to-Frequency Converters, Ref. 1 ), famed designer Jim Williams cataloged five fundamental techniques for voltage to frequency conversion. One of those five is reproduced in Figure ...
Designers charged with creating precision analog front ends and signal chains know that the performance of the voltage reference whether a discrete standalone device or one that’s embedded in a component such as the analog-to-digital ...
A common problem for digital potentiometers (DigiPots) is the effect of wiper resistance, which produces quite noticeable non-linearities of regulation at both ends of the resistance range. These effects also lead to an increased tempco in these ...
Given their generally low cost, small size, robust construction, accuracy, versatility, and sensitivity, it’s no wonder that basic negative temperature coefficient (NTC) thermistors rate among the most popular temperature sensors available. ...
Abstract This article details a method of generating dual-output voltage rails that provide both the positive and negative rails for a device power supply (DPS) while requiring only one bidirectional power supply. The traditional method of powering ...
Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts. Also, unless the converter is driven differentially, the noise ...
Abstract This article outlines the current methods used to enable true power-on (TPO) multiturn sensing capabilities and introduces a new simplified solution that is set to reshape both the industrial and automotive position sensing markets. The ...
Large currents flowing in a length cable can be measured using the voltage drop along the cable. It eliminates the need for a bulky shunt or expensive magnetic measurement method. Accuracy is limited however because of the +0.39%/ C tempco ...
