Patent ID: 7206240

Claim:
A sensing circuit, comprising: a sensing device having an input node and a first precharging path coupled to the input node; and at least one second precharging path, wherein each second precharging path is coupled to the input node through a pass circuit; wherein the first precharging path and the at least one second precharging path are adapted to be concurrently activated during a first portion of a sensing operation while the pass circuit is activated; wherein the at least one second precharging path is adapted to be deactivated during a second portion of the sensing operation while the pass circuit and the first precharging path remain activated from the first portion of the sensing operation; and wherein the first precharging path and the at least one second precharging path are adapted to be concurrently deactivated during a third portion of the sensing operation while the pass circuit remains activated from the second portion of the sensing operation.
