Working with the CMOS inverter approximate switching time equation. Attachments in Word.
The circuit shown in Figure B2 is of a CMOS inverter driving a capacitive load. VDD represents logic level "1" and zero volts logic level "0". M1 is an nMOS device and M2 is a pMOS device. (a) Calculate the approximate switching time that is obtained if the output is loaded by a capacitance, CL , of 0.2 pF due to interconne ...continues
How would I design a circuit to test BJT transistors?
Amplifier Transfer Function (Simple)
Why is 1nF a transitor internal resistance? Please show the appropriate small signal equivalents. Thanks!
Feedback Amplifier Analysis (solution is provided, looking for more conceptul help)
The solution to this problem is provided. I'm mainly just looking for clarification on some things. I don't understand why the 10k (Rs - it's not actually labeled Rs but it's the one in series with Vs) resistance is not being taken into account in parts (e) & (f) and then in part (i) a completely different Ri is being used to ca ...continues
Feedback Amplifier Analysis (more :) ) - again solution provided, need conceptul help
Solution is provided (those in part (a) it says series-shunt which is incorrect, it should say shunt-series). Looking for conceptul explanations. In part (e) when the gain is being calculated, why is the 2k (Is resistance) not being included? how would i know when / when not to include it? Also, got vo/vo1 is this a universal wa ...continues
For the two problems in the attachment.I have been trying to calculate Vbe but the value I'm getting is always > 0.7V, which is wrong.
The solution is included. Only further explanations are required. I don't understand how the 2-port parameters in part 3 work. For the gain in part 4, what is the theory for dividing it by Ro + the top. If you could just go over it that would be great! Parts 5,6,7 make sense. Simple, easy to follow explanations please :)
Finding resistance for differential stages
Questions about a two stage amplifier
I am trying to get more practice working Basic BJT Amplifer problems for my Electronics class. However, I don't know if I am doing the problems correctly. Please give me (at least) 3 worked out problems with explict explanations of every step from the DC KVL equations, the Hybrid pi values, the small signal equivalent circui ...continues
