True logarithmic amplifier with adaptive temperature compensation

The invention provides an adaptive temperature compensation true logarithmic amplifier, which comprises an input matching network connected with an external signal input end and a continuous detection type logarithmic amplifier respectively; the continuous detection type logarithmic amplifier is used for carrying out demodulation and logarithmic processing on the signal input by the matching circuit; the self-adaptive temperature controller is used for compensating the output signal according to the temperature change; the input end of the limiting amplifier is connected with the output end of the input matching network, and the limiting amplifier is used for outputting signals with stable amplitude; the input end of the amplitude-adjustable amplifier is connected with the limiting amplifier and the output end of the linear voltage and current converter, and the amplitude-adjustable amplifier is used for outputting a signal which is in logarithmic relation with an external input signal, keeps the frequency an
