Question:-
An n-type MOSFET and an npn BJT are biased so that Ic = ID = 1 mA, VGS = 1.3V and VBE = 0.7V. Threshold voltage for the MOSFET is 0.8V and thermal voltage at the ambient temperature is given to be 25 mV Transconductances of the BJT and the MOSFET are
Option (A)
gmBJT = 40 mA/V and gmMOSFET = 4 mA/V
