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.
