Q. What should be the value of unity gain frequency for a short circuit CE transistor with gain of 30 at
4 MHz and cut-off frequency of about 100 kHz?
40 MHz
80 MHz
120 MHz
150 MHz
80 MHz
120 MHz
150 MHz
Dear Student,
As given the values, Al = 30 and f = 4MHz. and the cutt- off frequency, fc= 100KHz
So, the unity gain frequency, fT= Al x f
= 30 x 4 x 106
= 120 MHz.
Hence option (c) is correct.
