发明名称 Current sense amplifier
摘要 A high-speed current sense amplifier has complementary reference cells and load devices that eliminate capacitive mismatch contributions. The current sense amplifier includes a voltage comparator, a first clamping device coupled between a first input of the voltage comparator and a first input signal node. The first clamping device is coupled to a reference voltage. A second clamping device is coupled between the second input of the voltage comparator and a second input signal node. The second clamping device is also coupled to the reference voltage. A current mirror is coupled between the first and second input of the voltage comparator and is coupled to an active capacitance balancing circuit. The active capacitance balancing circuit may be combined with the voltage comparator. Equalization devices may be coupled between the first and second inputs of the voltage comparator, and between the first input signal node and the second input signal node.
