The advancements of MOS Integrated Circuit technology have led to higher levels of system integration on silicon. Open loop differential amplifier circuits are frequently used as comparators to interface analog signals to digital processing circuits in applications such as the detection of transition edges, voltage levels, etc. Hysteresis in the switching threshold, as shown in Fig 1, is desirable to reduce the instability of the comparator output when the input signal level is near the comparator threshold and electrical noise is present in the system.
