摘要：

A novel technique to implement class AB differential amplifier input stages is proposed. It is based on the use of Winner-Take-All circuits for achieving dynamic current boosting, and is well suited for low-voltage operation. Experimental measurements of an OTA using this technique, fabricated in a 0.5-mu m CMOS technology, show a slew rate of 92 V/mu s for an 80-pF load and 120 mu W of static power consumption.
