Figure 2

Circuit partitioning. The figure illustrates the partitioning of a simplified operational amplifier composed of 19 MOSFETs and one ideal voltage source of zero Volts into two partitions (P1 and P2). The six coupling nodes (VDD, N1, N2, N3, N4, and VSS) are marked by arrows. The first partition P1 has five internal nodes and one current variable (due to the MNA approach each voltage source has one current as MNA variable in the system), whereas the second partition P2 has six internal nodes. The whole circuit has 17 nodes (and thus 18 MNA unknowns) in total.
