The MOSFET differential pair is a key part of many analog circuits e.g. opamps, comparators, LDOs, etc. A differential pair applies gain to the difference between two signals and has many advantages over single-ended amplifier circuits, e.g. noise reduction and suppression of common-mode signals and DC offset. However, these advantages rely upon precisely matched circuit… Read More »Balancing analog layout parasitics in MOSFET differential pairs
