Hi I have found the the threshold frequency for this equation but I have one more problem. Which Planck constant should i use to solve this question? What I mean is because in my previous question(not shown here) , I was asked the determine the Planck constant through experimental result and I...

Work function is eV but Planck constant has Js , ev/s

Homework Statement I am trying to plot a graph of stopping voltage against frequency The given equation is eV0 = hf - w0 So i need to change it to the form of y = mx + C in order to plot this graph V0 = h*f/e - w0/e V0 = h/e * f - w0/e -- > V0 = y , m(gradient) = h/e , x= f and -w0/e = C (y...

Hmm what is hV0 ? I mean the h Is it Planck constant? h? Or other thing?

Experimental investigation From the collected data , I have plotted a stopping voltage versus frequency graph. I have the following values work function (eV) , Planck constant , threshold frequency I need to know what does the matal surface inside the h/e apparatus photodiode refer to in order...

Homework Statement Find the minimum amount of energy required to eject electron from the metal surface inside the h/e apparatus's photodiode. Homework Equations Photoelectric Effect Equation E = hf = hc/ wavelength = eV0 The Attempt at a Solution Does the metal surface inside the h/e...

There don't seem to be a common terminal between the input and output if I look at M2 only.The only common terminal I see between the input and output is between M1 and M2 terminal where the body of the M1 (output) is connected to the input of M1

I am looking at the amplifier at M2

Input is connected to the gate , Output is connected to the drain. Source is connected to neither input or output

The source is connected to the gate and Output is connected to the drain

I would also like to check if this is a configuration of a Common source with source degeneration single stage amlifer?

hmm good guess meaning is ID , M2 = 4mA correct or wrong? For channel length modulation In the picture it says that the channel length modulation is equal to 0 for channel length modulation M1 and channel length modulation M2.

I have another question for this. I am asked to find the small signal parameter of the 2 MOSFET . The formula are Output resistance in the small signal equivalent circuit of a MOSFET operating in the saturation region is given as R0 = 1 /(channel length modulation * Current ID) I have ID value...

Sinc k2 = 2k1 , I2 = 2I1. I2 = 4mA?

Hi So I find the value for Vgs by subbing in Vth and I D,M1. Once I gotten the value of Vgs , i sub this value into the equation to find i D,M2 with a k2? Am I correct?
