A sense amplifier may be operable to form a current-mirror reference using a first PMOS transistor and a NMOS transistor. Currents at a first internal terminal and a second internal terminal may be generated based on the current-mirror reference. Voltage signals at the first internal terminal and the second internal terminal may be generated based on received differential input signals and the currents at the first internal terminal and the second internal terminal. The sense amplifier may limit voltage excursions of the voltage signals at the first internal terminal and/or of the second internal terminal using a pair of cross coupled PMOS transistors, respectively. Voltage signals at a third internal terminal and a fourth internal terminal may be generated based on voltage signals at the first internal terminal and the second internal terminal. An output signal may be generated based on the voltage signal at the fourth internal terminal.
