Hello,
in the image down is the known wide swing mirror.
Kindly I need your discussion about layout this circuit.
1. I have two approaches, in the first one I would layout M1 and M2 seperately from M3 and M4 then I connect the two matched array
in the second approach, I would layout M1, M2, M3 and M4 in one matched array, but this is making the connection more complex.
Therefore I need please your opinion about it, which one of the approaches should be better.
2. the diode connected transistor M5 is actullay located in the biasing circuit from this mirror, should be a problem ?
3 . I am usually matching my arrays in one row like for example ABBA or in two rows like ABBA/BAAB, I never go to higher diamentions like four rows althaugh it is supposed to give better matching but the complexity of connection and te parasatic associated to it will be also high, what you think ?
Thank you in advance
