Q. |
The major advantage of the trans- impedance configuration over the high- impedance front end is |
A. | greater bandwidth |
B. | less bandwidth |
C. | greater dynamic range |
D. | less dynamic range |
Answer» C. greater dynamic range | |
Explanation: greater dynamic range is a result of the different attenuation mechanism for the low-frequency components of the signal. this attenuation is obtained in the trans-impedance amplifier through the negative feedback and therefore the low frequency components are amplified by the closed loop. this increases the dynamic range. |
