WebJan 28, 2024 · One benefit of the resistive nature of MOSFETs is that you can parallel them to reduce the total on-resistance. Bipolar transistors will current-hog; that is, tend to take a little more current,... WebWhen running SPICE DC simulations one could often see two types of MOSFET transistor operating point parameters for the channel resistance printed by the simulator. These often have different names depending on model versions spanning a range: ron, rout, rds, rd, 1/gds – these are at first sight ambiguous and could be a source of confusion.
