A new compact low-power high slew rate class AB CMOS buffer
نویسندگان
چکیده
In this paper a new compact CMOS class AB buffer is presented. Its simple implementation relies on the use of the Flipped Voltage Follower (FVF) [ I ] . Simulation results from a 0.35 pm CMOS technology are presented that prove the operating principle under low-power conditions. This buffer can also find application in testing of analog CMOS VLSI circuits, as the input capacitance can be very low without diminishing its output drive capability.

A New Low-Voltage, Low-Power and High-Slew Rate CMOS Unity-Gain Buffer
Class-AB circuits, which are able to deal with currents several orders of magnitude larger than their quiescent current, are good candidates for low-power and high slew-rate analog design. This paper presents a novel topology of a class AB flipped voltage follower (FVF) that has better slew rate and the same power consumption as the conventional class-AB FVF buffer previously presented in liter...

A rail-to-rail class-AB CMOS buffer is proposed in this paper to drive large capacitive loads. A new technique is used to reduce the leakage power of class-AB CMOS buffer circuits without affecting dynamic power dissipation .The name of applied technique is LECTOR, which gives the high speed buffer with the reduced low power dissipation (1.05%) and reduced area (2.8%). The proposed buffer is si...

A qualitative analysis of different parameters such as Phase noise, Slew rate and tranconductance by using power gating reduction technique is presented. The circuit achieves the large driving capability by employing simple comparators to sense the transients of the input to turn on the output stages, which are statically off in the stable state. The effect of the different number of transistor...
متن کاملHigh Slew Rate Micro-Power CMOS OTA with Class AB Input stage - Circuits and Systems, 1997. Proceedings of the 40th Midwest Symposium on
The design of a new single stage class AB operational amplifier is presented. Amplifier incorporates an input differential pair with minimum current selector and common-mode feedback to control the tail current. It shows small-signal behavior of a simple OTA, while class AB feedback provides high slew rate when large input signals are applied. Prototype circuit was manufactured in 2pm analog CM...
