| titleOfInvention | Analog / digital conversion circuit with scaling |
| abstract | (57) [Abstract] [Purpose] In an analog / digital conversion circuit that performs scaling so that the amplified analog signal is always close to full scale, regardless of the level of the input analog signal, until the maximum sensitivity is reached. Save time. [Structure] A scaling amplifier circuit 2 is provided with a plurality of amplification degree variable switches S1 to S4. Amplified analog signal S The AMP is divided into a plurality of stages by the voltage dividing comparators CP1 to CP7. The amplified analog signal S AMP is peak-held by the peak-hold circuit 10, and the differential amplifier circuit 11 The differential voltage V D is generated by and is sent to the control circuit 12. Based on the level of the difference voltage V D , the control circuit 12 causes the comparator circuit 13a to 13c and the logic circuit 14 to directly set the most significant digit of the digital code by the decoding circuit 4 among the plurality of switches S1 to S4 to "H". Turn on only one switch Control to |
