Step of 6 5.066P Calculate the overdrive voltage. =0-(-2) =2V Step of 6 Case (i): For = the voltage So, the transistor is operating in triode region. The equation for drain current is, Substitute for 0V for -2V for V, and 1V for in the equation. Therefore, for = IV value of drain current is, Step of 6 Case (ii): For the voltage = So, the transistor is operating at edge of saturation region. The equation for drain current is, Substitute for 0V for -2V for V, 0.02 V⁻¹ for 2. and 2V for in the equation. =416x10⁻⁶ Therefore, for value of drain current is Step of 6 Case (iii): For the voltage So, the transistor is operating in saturation region. The equation for drain current is, Substitute for 0V for -2V for V, 0.02 V⁻¹ for and 3V for in the equation. Therefore, for value of drain current is Step of 6 Case (iv): For =10V the voltage So, the transistor is operating in saturation region. The equation for drain current is, Substitute for 0V for -2V for V, 0.02 V⁻¹ for and 10V for in the equation. Therefore, for = value of drain current is Step of 6 In all the four cases, the relation between drain current and width-to-length ratio is W If width is doubled with L the same, then drain current also doubled in all the four cases. If width and length are doubled, then there is no change in drain current in all the four cases.
