Current sense amplifier
A current differential sense amplifier for static RAM cells which couple one of a pair of bit lines to a current source for a high speed read operation. The sense amplifer has current mirrors which amplify the current on each of the bit lines. The amplified currents are fed into an active load which...

| Zusammenfassung: | A current differential sense amplifier for static RAM cells which couple one of a pair of bit lines to a current source for a high speed read operation. The sense amplifer has current mirrors which amplify the current on each of the bit lines. The amplified currents are fed into an active load which has an output node which rises and falls in voltage depending upon the current mismatch. An inverter connected to the output node speeds the slew rate of the node. |
