Summary:A logarithmic amplifier (200) includes a logarithmic current preamplifier circuit (202) and a logarithmic amplifier circuit (204). The logarithmic current preamplifier circuit (202) includes an inverting input terminal (206A), an output terminal (206B), and a first diode (210). The first diode (210) is coupled between the inverting input terminal (206A) of the logarithmic current preamplifier circuit (202) and the output terminal (206B) of the logarithmic current preamplifier circuit (202). The logarithmic amplifier circuit (204) includes an inverting input terminal (212A), an output terminal (212B), and a second diode (214). The inverting input terminal (212A) of the logarithmic amplifier circuit (204) is coupled to the output terminal (212B) of the logarithmic current preamplifier circuit (202). The second diode (214) is coupled between the inverting input terminal (212A) of the logarithmic amplifier circuit (204) and the output terminal (212B) of the logarithmic amplifier circuit (204). 一种对数放大器(200)包含对数电流前
