Abstract:
A high-speed single ended sense amplifier circuit comprising:a pre-charge circuit coupled to a sense amp input signal, wherein the pre-charge circuit is operable to pre-charge the sense amp input signal to a known state when the sense amplifier circuit is operating in a first mode; a sensing inverter circuit coupled to receive the sense amp input signal, the sensing inverter circuit being operable to generate a sense amp output signal; a feedback inverter circuit coupled to receive the sense amp output signal and weakly drive the sense amp input signal when the sense amplifier circuit is operating in a second mode; and a control circuit coupled to the feedback inverter circuit, the control circuit being operable to set the input of the feedback inverter to the complement of the known state when the sense amplifier circuit is operating in the first mode.
