Abstract
A sense amplifier having a sampling circuit to sample the amplifier input signal; a reference node storing a reference signal corresponding to the input signal; and a timing circuit activating the sampling circuit for a predetermined interval, and admitting the reference signal to the reference node. The sense amplifier also can include a pump capacitor substantially maintaining a value of the reference signal; and a gain circuit coupled with the reference node and disposed to adaptively adjust gain of an output signal produced by the sense amplifier. The sense amplifier can be a single-ended sense amplifier.
Claims4
A sense amplifier, comprising:
- a. a sampling circuit receiving an input signal to the sense amplifier;
- b. a reference node storing a reference signal corresponding to the input data;
- c. a timing circuit activating the sampling circuit for a predetermined interval, the sampling circuit admitting the reference signal to the reference node thereby.
