Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
The gain-bandwidth product (GBW) of an op-amp is a constant and is defined as:
\(\text{GBW} = \text{Gain} \times \text{Bandwidth}\)
For unity gain (gain = 1), the bandwidth is equal to the GBW.
Given:
Bandwidth = 5 MHz at Gain = 20
Calculation:
\(GBW= 20 \times 5~\text{MHz} = 100~\text{MHz}\)
Therefore, the unity gain bandwidth = 100 MHz
