Abstract
The invention discloses a broadband logarithmic detector with high dynamic range, comprising a low noise amplifier, a compensate detection unit, a current summation and driving unit, an N-stage clipper amplifier and an N-stage detection unit. The invention improves the detection sensibility of the overall detector by adding a low noise amplifier before the first-stage clipper amplifier and extends the dynamic detection range of the overall detector through combination of the low noise amplifier and the compensate detection unit.
