A BJT transistor is biased such that it has a collector current IC = 1mA independent of temperature. At a temperature of 62 degree Celsius, the transconductance (gm) (in mS) is equal to .....
Hint: You can use the approximate value of VT at room temperature to calculate the value of VT at any other temperature:
VT (at temperature To in Kelvin) = 26mV * To/300
gm = IC/VT.
