Can you guys tell me how to do warm tonic? [Copy link]

There are two solutions I know of. One is to use a thermistor to make a feedback circuit. Or use good components. Or use physical solutions such as aluminum plate PCB. The second is to measure the temperature and compensate with software. Experts, do you have any other solutions? For example, using circuit structure or something.

Where do you apply warming?

"Are there any other solutions?" Another method is to heat and maintain a constant temperature, such as an oven-controlled crystal oscillator.

I don't understand

I would like to ask you, the temperature rise of semiconductors is inevitable, is there any solution to compensate for the temperature rise using a method similar to differential? I would like to take advantage of this rising tide lifts all boats method.

Of course there is. First of all, the differential amplifier is two tubes that compensate each other. For example, in the complementary push-pull amplifier circuit, two diodes are often connected in series between the bases of the two tubes to provide the base bias of the two tubes. The compensation is also based on the fact that the temperature characteristics of the diodes are similar to the temperature characteristics of the transistor emitter junction.
