Abstract :
A buffer that can source or sink up to 10 mA with a slew rate of 130 V/μs in a series RC load of 500 Ω and 12 nF is introduced. The buffer has a standby current of 400 μA which is reduced to 50 nA in less than 100 ns in power-down mode. It operates with a 2.7-V supply and is designed for personal communications applications such as Digital Enhanced Cordless Telecommunications (DECT). The adaptive biasing technique employed in this design makes it suitable for other applications like high-speed sample-and-hold or transconductance stages
