Hello all,
I have some queries regarding the layout design for a complex circuit design. I have to design a cascaded pair of emitter follower (EF) and differential amplifier (DA) circuit blocks, where the outputs (both +ve as well as -ve) of the former block have to be connected to the inputs(+ve and -ve) of the latter block. My entire layout design consists of M1 and M2 layers (mostly). My doubt is that, if I have to make the connections which I have mentioned, my cascaded design becomes more complicated (with ugly wire connections between layers). Also, in order to take into the current flow, its bit difficult to make the design. I have attached my cascaded pair circuitry (both schematic as well as layout design) along with this post. To understand my circuit design a bit easier, I have considered only a single cascaded pair (As a whole, I need to make 3 pairs of the cascaded pair).
I have already made the connection between voutn(-ve output voltage) of EF to vinn (+ve input voltage) of DA. A quick response would be really appreciated. Thanks in advance.
