Current-mode sense amplifier |
摘要 |
A current-mode sense amplifier includes a current mirror circuit having an input branch controlled by a current input signal to be sensed and an output branch connected to a capacitor. The output branch and gates of current mirror transistors are connected to transistors for precharge operation. The sense amplifier needs no reference current, provides a low component count and is noise resistant.
