### 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 ...

### 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?

### 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 ...

### 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 ...
