Question

A Hartley oscillator uses FET with gm of 2 ms and rd = 2 K&Omega;. The total coil inductance is 10 &mu;H with turns ratio of input to output side of 1 : 10. It is tuned with a 50 pf capacitor. Find frequency of oscillations, amplifier gain margin in dB.-A-7.11 MHz, 13.97 dBB-7.3 MHz, 14.1 dBC-6.93 MHz, 12.9 dBD-7.4 MHz, 13 dB-A-7.11 MHz, 13.97 dB

APTITUDE CRACK · Accepted Answer

The correct option is  A 7.11 MHz, 13.97 dB  = 7.11 MHz μ = gm x rd
