I am unable to understand the working of the below circuit and how it act as amplifier.
- Enable the SAEN signal i.e. turning it high.
- Let us assume that we get DL as 1 and DLB as 0. Actually it will be (Vprec+deltaV) and (Vprec-deltaV)
- Now the A nMOS is conducting and we will get both pMOS gate as Logic 0.
- This will make both nodes at A and B as 'Strong +".
What will be the level at A as the pull up pMOS will pull it up and pull down nMOS will put it down. And what is the use of the current mirror? And how does it amplify?
