Low frequency asymmetrical led blinking circuit, lacking thermal stability

I'm trying to use a NE555D to achieve a 500ms on, 1500ms off, duty cycle. The exact timing is not that important(+-20%). But my problem is that when the temperature changes it greatly effects the blinking rate. blinks faster when it is hot and stops…

Voltage reference drift in ppm/°C to V/°C

How does one convert drift in ppm/°C to V/°C? Assume a 5 V voltage reference has an output voltage drift of 12 ppm/°C. What is the output voltage drift in volts for a target temperature of 85°C?

Max31855k - fluctuation and drift

I'm using a b 31855k breakout board (a chinese one at that) with the olimex A20 and a K-type thermocouple (which works OK on another device with the 31855k). The problem is, that the thermocouple temp reading fluctuates wildly (up to +- 10deg C) and…

Temperature drift on volatge divider built with resistors from the same series

I am in the process of designing a data acquisition device that will be used outdoors, with temperature swings of around 30 degrees. For this i need to scale the input to a voltage suitable to the adc and reference i am using, the initial offset of…

Current source temperature stability

I want to implement an interesting current source topology that I came across recently (picture below). It shows very good performance in simulation and the only thing I am concerned of is its temperature stability. As far as I understand the key is…

How to compensate for shunt resistor thermal drift?

I'm working on a electronic load and below schematic is the simplified version of it. simulate this circuit – Schematic created using CircuitLab The problem is the thermal drift in resistors and op amp but what makes several mA drift is the shunt,…

IGBT Temperature Drift: How to Achive Stability?

I remember the BJT transistor circuits are designed to compensate for the fact that the parameters of the transistor change with the temperature. I could not find similar ready-to-use solutions for the IGBT. My circuit should work in the switch…
