Hi All,
I have made a current mirror circuit as attached below with Rin as 5K,Vin =15Vdc
.
Vo = 24 to150Vdc.
IRef=(15-Vgs)/(5K+RDS)
As per my calc IRef=2.2mA Approx.
I assume the same current should mirrored in Iout irrespective of the voltage given @ Vo.

Re: variation expected in Current mirror due to MOSFET mismatch
Hi Zapper,
How to find whether these MOSFET is perfectly matched or not?
Part no: Si7956DP
Re: variation expected in Current mirror due to MOSFET mismatch
Hi Zapper,
With Wilson Current mirror(MOSFET) can the accuracy of the current mirror be improved compared to simple current mirror(MOSFET)?
Hi All,
What is the variation expected in Current mirror(Simple Current Mirror) due to MOSFET mismatch? what are the other parameters that can affect the accuracy?
For example if a current mirror is designed for 10mA. How much is variation expected due to MOSFET mismatch?
Hi,
In the datasheet, VGS min=2 & max=4V.
On What basis Vgs would vary?
on keeping the Vdd within +/-1% accuracy, R +/-1%, with varrying Vout. What is the variation expected in Vgs?
I guess my question was not clear.
Let me split my questions.
Assume VDD=10V.
Requirement for Iout = 10mA.
What should be R value?How to calculate it?
MOSFET PN: IRFL210
**broken link removed**
how to calculate the Resistance of M1 & M2 in saturation mode ?
What is the current though M1 & M2? Ideally it would be Iref but what would be practical case?
IRFL210--MOSFET part number
Hi All,
I'm trying to replace MOV(130VAC,21Joule) used in circuit with transorb(rated for 170V,1500W).
So i want to convert Watts to joule & compare the energy of Transorb with MOV
Appreciate your Help.

Hi All,
I am a new to skill programming........I would like to learn skill
program... can you tell me how to execute a skill code....
I tried skill load filename.il in CIW.........dint work.......
Kindly clarify me.....
small program to display a message using skill code & executing...
Help Needed:
Hi,
Iam a newbie,trying to learn skill programming(cadence).
Kindly help me in understanding.
Can anyone tell me how to execute skill program? with an simple example plz.
Also suggest me some tutorials.
Thanks in advance
