ABSTRACT:
A temperature dependent amplifier which may be used as a system building block in temperature compensation applications is disclosed. A temperature dependent signal source generates a first order temperature dependent signal which is multiplied by an input signal and divided by a temperature reference signal to produce an output which varies in direct proportion with temperature changes. The input signal is multiplied by the temperature reference signal and divided by the temperature dependent signal to produce an output which varies inversely proportional to temperature changes.
