Abstract:
In order to improve the noise ratio and stability of the amplified small-signal in microwave-induced thermoacoustic tomography,an amplifying circuit with wide band and high voltage gain is designed in this paper.The results show that the voltage gain is up to 80dB and the bandwidth is about 7MHz.
