how to make the temperature compensate circuits?

It depends what you want to compensate. It can be frequency, working point of a transistor amplifier etc... For temperature compensation you need first of all suitable element (transducer) which changes it's properties with temperature (diode-voltage drop when forward biased, NTC-resistance, PTC-resistance ...). This element has to be part of circuit which does compensation. Result of compensation is less temperature instabilities of some parameter of circuit or device.

You usually need PTAT (Proportional To Absolute Temperature) or bandgap circuitry on integrated devices.
