I want to perform the small signal AC analysis of the circuit. To calculate gm. I need IC ,ie the DC quiescent collector current. But in the differential amplifier stage, the AC input voltages are not connected via capacitors....So while performing DC analysis ,we cannot open circuit the AC...
QThe transistors have finite β and an infinite early voltage. Derive the expression for Io in terms of Iref and β.
In this question Io has to be represented in terms of Iref.... The solution matches to that given in text book. But they have perhaps done it without considering the doubled area...
I am studying about analysis of multiple diode circuits and came across this article. It seems that this article is part of some book. If anyone has ever used this book, it would be highly helpful if you would be able to tell which book's part is this. Thank you.

I had calculated the first I(D1) to check if current through it is +ve or -ve. But that is perhaps not necessary and wrong as you pointed out that as we have determined D2 is off, I(D1)=1.86+0=1.86 mA in the first place only. Thank you sir for helping me with it. :grin:
Q. Cutin voltage for each diode=0.7V.
Determine current throught D1 and Vo for
(a) R1=10 kohm, R2 =5 kohm. Ans(I(D1)=0.93 mA, Vo=-15V)
(b) R1=5 kohm, R2 =10 kohm. Ans(I(D1)=1.86 mA, Vo=-15V)
My approach
(a)First considering both the diodes connect.
Let the voltage of the node where n...
I am trying to find z transform of nu(n)
In that I encounter the following problem:
How do I find the simplification of the following series?
z^-1 + 2z^-1 + 3z^-3 + ...... to infinity
Please describe the mathematical steps.
How to write testbench for this code if we want to implement it in vivado HLS?
We are new to vivado HLS. It seems that it is mandatory to write testbench for a c code in vivado hls. How to write a testbench for this code?
We have come to know that we have to omit the printf statements. What...
We have found a code for implementing LMS algorithm. However we cannot find any of the components of LMS algorithm in the simulation results viz input signal x(n), desired signal d(n),error signal e(n),output signal y(n).Only signal result is there.What value is result representing?Also after...
Re: How to implement LMS algorithm in vhdl?
How to use ufixed when it involves multiplication a number of times?(VHDL question)
We have to implement the following LMS equations in vhdl in a loop. y=x1w1+x2w2; w1=u*x1*e+w1; w2=u*x2*e+w2; e=y-x; However u is a floating point number and have to...
Sir Understood. But sir why is then a relative separation is there between the signals. Shouldnt they all start from the same instant after facing a particular delay(in this case after 360 clock cycles)?
We are trying to generate a noisy sine wave signal, that will be phase shifted three times to generate signals s1,s2,s3 and s4. For that we have created an array sine2 that will hold the noisy sine wave signal, and we will shift it according to our convenience by changing its index.
The problem...
Sir we were successful in adding pseudorandom noise sequence to our sine wave, but now we are trying to add Gaussian noise. The code and the simulation results for ADDITION OF PSEUDORANDOM NOISE SEQUENCE TO SINE WAVE IS GIVEN BELOW:
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use...
