- Stephen WoodwardThe ubiquitous variable resistance circuit network shown in Figure 1 Figure 1. Classic adjustable resistance; R MAX = R S + R R ; R MIN = R S . But a sticky question remains: What if the polarity of the V A V B differential is subject to reversal? ...Dec 17, 2024
- Nick CornfordUsually, noise annoys. Occasionally, it can be a valuable tool. Surprisingly, there is a whole palette of noise colors [ 1 ]. This design idea (DI) shows good ways of generating the commonest and most useful ones, which are white [ 2 ] and pink [ 3 ...Nov 28, 2024
- Stephen WoodwardFrequent contributor Nick Cornford recently published a delightfully clever design idea ( Reference 1 ) using a platinum RTD calibrated to output a 1 mV/ C signal that’s perfect for direct readout via a standard DMM I thought Nick’s ...Oct 1, 2024
- Stephen WoodwardPulse width modulation (PWM) is a terrific basis for digital to analog conversion. Credit goes to features like simplicity and (theoretically) perfect differential and integral linearity. Unfortunately, PWM’s need for ripple filtering tends ...Aug 29, 2024
- Stephen WoodwardA silly simple and ubiquitous circuit network is a variable resistance consisting of the series connection of a manually adjusted rheostat-connected pot and fixed resistor shown in Figure 1. Figure 1. Classic variable resistance with the series ...Aug 7, 2024
- Stephen WoodwardFew methods for analog to digital conversion are more “mature” than the classic combination of a voltage-to-frequency converter (VFC) with a counter. VFC digitization is naturally integrating, so good noise rejection is inherent, as is ...Jul 24, 2024
- Steven HendrixFor a recent design project, a robust power supply was needed to control the gates of high-side FETs. Optocouplers readily translate the logic signals up to the correct control voltages to drive the FETs. However, to ensure that the FETs turn on ...Feb 14, 2024
- Thomas ScarboroughThis Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a similar resistor-FET-logic. Further, ...Dec 25, 2023
- Stephen WoodwardLow-cost monolithic precision adjustable voltage references are available in multiple families from multiple manufacturers, but this isn’t true for adjustable precision current references. That’s unfortunate, because while most ...Oct 19, 2023
- Stephen WoodwardSelf-powered isolation amplifiers, which need no external isolated power supply, provide versatile and convenient interfaces in many applications that require galvanic isolation of the signal source. Examples of such applications include circuits ...Jul 27, 2023
