Thank you for the reply. Could you also provide an answer to the second part of the question, "What would be the operating regions of both the transistors in the current mirror circuit and how to select the resistor value in the current mirrored branch?" How to find the region of working of both...
I have a few basic doubts regarding this USB to UART bridge IC - XR21B1424 - https://www.maxlinear.com/ds/xr21b1424.pdf
My questions are just from the hardware perspective.
1. This IC converts USB protocol to UART protocol at the available 4 output channels, right? Is there any software...
I have read wikipedia and other websites regarding the diode connected BJT.
But I am not clear on where should we use a diode connected BJT or like what is the purpose.
My questions :
1. Where is a diode connected BJT used? Like, in what type of requirements do we need to use a diode...
Sorry my bad. I turned up to voltage to 36V and told the current to be around 385uA and 380uA.
For 24V,
the currents are 256.77uA, 253.81uA and through R0012 is 2.93uA
I found the The Input Leakage current in the Microcontroller datasheet as 0.005uA to 0.5uA on Page 29.
So, does this mean, that would be the maximum current through the R0012 would be 0.5uA?
If so, What would be the current throught R0010 and R0011?
What would be the voltage at the...
Below I have attached a circuit which divides the voltage and gives the output to an Input Pin of the Microcontroller.
Input Voltage = 24V
The Resistor R0012 is for current limiting Purpose. And the Zener Diode breakdown voltage is 5.1V.
The Microcontroller which I am using is - **broken link...
So, from your reply what I understand is that, for a 27V Zener, we can Apply as high Voltage as possible, provided we don't send much current through the Zener (the current which can be limited by the Current Limited Resistor). Is it correct?
Please correct me if I am wrong.
For example, If for...
In many Zener Diode datasheets, I have witnessed that in the Absolute Maximum Ratings section, they don't include the "Maximum Voltage" that can be applied to the Zener diode. If the applied voltage crosses the Zener breakdown voltage, then the voltage will start to conduct and will enter in the...
How much Voltage will be present at the GPIO pin for a Microcontroller which has a Vcc(Input Supply voltage) of 3.3V ?
Suppose I need to connect an LED at this GPIO what are the factors or calculations that I have to consider ?
And, How much voltage should I apply to an LED to turn it on? What...
I am finding very difficult and confusing to understand the concept of The Open Dain or Open collector configuration.
Can someone explain in clear and simple English with an example.
Can u please tell me how the problem was solved ?
I am finding difficult to write the KVL for the circuit ?
Which loop must be considered first and how the KVL was written to solve this problem ?
I am unable the solve this problem.
Could someone help to find out which diode is ON and which is OFF and tell me how to find out ?
I am unable to write the KVL.
And help to find the current "I"
Thanks in advance! :)
In a circuit with Capacitance and Inductance with an AC source, I see that when we calculate the value for the impedance of the capacitor and Inductor
there is a complex component "j".
What is the complex term and why is the complex term "j" included in the expression ?
Yeah. But when I want the input of the gate of the transistor(inside uC) to be 1, I connect it to the high voltage via the resistor. What would be voltage drop at a node after the resistor i.e., node before the input pin of uC ?
And, what If I want the pin to neither be in high state nor...
