Title:
DETECTOR DEVICE, AND AMPLIFICATION DEVICE, TRANSMISSION DEVICE, AND COMMUNICATION DEVICE USING THE DETECTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/024846
Kind Code:
A1
Abstract:
Disclosed is a detector device which is provided with: an amplifier (AMP1) which amplifies the voltage of an input electric signal and outputs the result; a first detector circuit (Det1) which outputs a first detection signal having a current corresponding to the voltage of the input electric signal; a second detector circuit (Det2) which outputs a second detection signal having a current corresponding to the voltage of the input electric signal; and a current adding circuit (SUM1) which receives the first detection signal and second detection signal as input and outputs a third detection signal having a current value obtained by adding the current values of the detection signals; wherein the input signal to be detected is divided, one part of the input signal is input to the first detector circuit (Det1), and the other part is input through the amplifier (AMP1) to the second detector circuit (Det2). As a result, a detector device having a wide dynamic range, and an amplification device, transmission device, and communication device using the detector device can be obtained.
