Adaptive bias circuitry used in OTA for improving Slew rate

[s_babayan]

Dear friends,

does anybody know anything about adaptive bias circuitry used in OTA for improving Slew rate ? If so, wouldyou plz leave me great books or papers or introduce them?? Thank you.

You have something in Maloberti book.

Adaptive Biasing

There is a ckt mentioned in a paper which detects the input signal rise and fall and changes the current to the load... try searching for High Slew Rate Opamp in IEEE Xplore

hi, maybe this paper can help you.

Low-voltage power-efficient adaptive biasing for CMOS amplifiers and buffers
