A sense amplifier utilizes a phase transition material (PTM) in conjunction with CMOS circuits to provide a precise sensing threshold. The sense amplifier can be used in memory applications to sense states of stored bits with high accuracy and robustness. In one sense amplifier, a first diode-connected transistor has gate and drain nodes coupled to an input node of the sense amplifier, a second transistor has a gate node coupled to the gate node of the first diode-connected transistor, and the PTM is coupled to the source node of the second transistor. In another sense amplifier, a first transistor has a gate node coupled to an input node of the sense amplifier, a PTM is coupled to the source node of the first transistor, and an output stage including an inverter is coupled between a drain node of the first transistor and an output node of the sense amplifier.
