| Q. |
Which of the statement is incorrect? |
| A. | at unity gain frequency the ce short circuit current gain becomes 1 |
| B. | unity gain frequency is the same as gain bandwidth product of bjt |
| C. | gain of bjt decreases at higher frequencies due to junction capacitances |
| D. | β- cut-off frequency is one where the ce short circuit current gain becomes β/2 |
| Answer» A. at unity gain frequency the ce short circuit current gain becomes 1 | |
| Explanation: gain bandwidth product for any mosfet is ft = gm/2π(cgs+cgd) thus gbp is approximately 5.9 mhz. | |
