The ideal transconductance amplifier has the following charcateristic:

Given, V_gs is the gate-source voltage, V_ds is the drain source voltage, and V_th is the threshold voltage of an enhancement type NMOS transistor, the conditions for transistor to be biased in saturation are:

Determine the current I_DSS for a JFET, if g_m = 4.2 mS at V_GS = -3 V. Given, V_P = -5 V.

For the circuit shown below if output current is 2 mA, then R = _______Ω.

The quiescent collector voltage of the given silicon transistor is ______. Given that: V_BE = 0.7 V, β = 100.

Consider a circuit shown in figure below,

If all the three transistors are identical and have very large value of β and V_BE = 0.7 V, then the approximate value of Resistance R₁ is equal to
